The parable of the “Lost Son” cannot be divorced from the opening two parables in Luke 15. Notice that this triad of parables is instructive regarding conversion—“lost and found”; “dead and alive.” Let’s be careful to utilize the parables of Christ the way they were intended. The “Lost Son” is a great picture of the way a gracious God seeks us when we are dead in our transgressions and sins. He draws us and makes us alive in Christ (Eph.2:1-10).

1 Samuel 19-21
Saul Tries to Kill David
19:1 And Saul spoke to Jonathan his son and to all his servants, that they should kill David. But Jonathan, Saul’s son, delighted much in David. 2 And Jonathan told David, “Saul my father seeks to kill you. Therefore be on your guard in the morning. Stay in a secret place and hide yourself. 3 And I will go out and stand beside my father in the field where you are, and I will speak to my father about you. And if I learn anything I will tell you.” 4 And Jonathan spoke well of David to Saul his father and said to him, “Let not the king sin against his servant David, because he has not sinned against you, and because his deeds have brought good to you. 5 For he took his life in his hand and he struck down the Philistine, and the Lord worked a great salvation for all Israel. You saw it, and rejoiced. Why then will you sin against innocent blood by killing David without cause?” 6 And Saul listened to the voice of Jonathan. Saul swore, “As the Lord lives, he shall not be put to death.” 7 And Jonathan called David, and Jonathan reported to him all these things. And Jonathan brought David to Saul, and he was in his presence as before.
8 And there was war again. And David went out and fought with the Philistines and struck them with a great blow, so that they fled before him. 9 Then a harmful spirit from the Lord came upon Saul, as he sat in his house with his spear in his hand. And David was playing the lyre. 10 And Saul sought to pin David to the wall with the spear, but he eluded Saul, so that he struck the spear into the wall. And David fled and escaped that night.
11 Saul sent messengers to David’s house to watch him, that he might kill him in the morning. But Michal, David’s wife, told him, “If you do not escape with your life tonight, tomorrow you will be killed.” 12 So Michal let David down through the window, and he fled away and escaped. 13 Michal took an image and laid it on the bed and put a pillow of goats’ hair at its head and covered it with the clothes. 14 And when Saul sent messengers to take David, she said, “He is sick.” 15 Then Saul sent the messengers to see David, saying, “Bring him up to me in the bed, that I may kill him.” 16 And when the messengers came in, behold, the image was in the bed, with the pillow of goats’ hair at its head. 17 Saul said to Michal, “Why have you deceived me thus and let my enemy go, so that he has escaped?” And Michal answered Saul, “He said to me, ‘Let me go. Why should I kill you?’”
18 Now David fled and escaped, and he came to Samuel at Ramah and told him all that Saul had done to him. And he and Samuel went and lived at Naioth. 19 And it was told Saul, “Behold, David is at Naioth in Ramah.” 20 Then Saul sent messengers to take David, and when they saw the company of the prophets prophesying, and Samuel standing as head over them, the Spirit of God came upon the messengers of Saul, and they also prophesied. 21 When it was told Saul, he sent other messengers, and they also prophesied. And Saul sent messengers again the third time, and they also prophesied. 22 Then he himself went to Ramah and came to the great well that is in Secu. And he asked, “Where are Samuel and David?” And one said, “Behold, they are at Naioth in Ramah.” 23 And he went there to Naioth in Ramah. And the Spirit of God came upon him also, and as he went he prophesied until he came to Naioth in Ramah. 24 And he too stripped off his clothes, and he too prophesied before Samuel and lay naked all that day and all that night. Thus it is said, “Is Saul also among the prophets?”
Jonathan Warns David
20:1 Then David fled from Naioth in Ramah and came and said before Jonathan, “What have I done? What is my guilt? And what is my sin before your father, that he seeks my life?” 2 And he said to him, “Far from it! You shall not die. Behold, my father does nothing either great or small without disclosing it to me. And why should my father hide this from me? It is not so.” 3 But David vowed again, saying, “Your father knows well that I have found favor in your eyes, and he thinks, ‘Do not let Jonathan know this, lest he be grieved.’ But truly, as the Lord lives and as your soul lives, there is but a step between me and death.” 4 Then Jonathan said to David, “Whatever you say, I will do for you.” 5 David said to Jonathan, “Behold, tomorrow is the new moon, and I should not fail to sit at table with the king. But let me go, that I may hide myself in the field till the third day at evening. 6 If your father misses me at all, then say, ‘David earnestly asked leave of me to run to Bethlehem his city, for there is a yearly sacrifice there for all the clan.’ 7 If he says, ‘Good!’ it will be well with your servant, but if he is angry, then know that harm is determined by him. 8 Therefore deal kindly with your servant, for you have brought your servant into a covenant of the Lord with you. But if there is guilt in me, kill me yourself, for why should you bring me to your father?” 9 And Jonathan said, “Far be it from you! If I knew that it was determined by my father that harm should come to you, would I not tell you?” 10 Then David said to Jonathan, “Who will tell me if your father answers you roughly?” 11 And Jonathan said to David, “Come, let us go out into the field.” So they both went out into the field.
12 And Jonathan said to David, “The Lord, the God of Israel, be witness!  When I have sounded out my father, about this time tomorrow, or the third day, behold, if he is well disposed toward David, shall I not then send and disclose it to you? 13 But should it please my father to do you harm, the Lord do so to Jonathan and more also if I do not disclose it to you and send you away, that you may go in safety. May the Lord be with you, as he has been with my father. 14 If I am still alive, show me the steadfast love of the Lord, that I may not die; 15 and do not cut off  your steadfast love from my house forever, when the Lord cuts off every one of the enemies of David from the face of the earth.” 16 And Jonathan made a covenant with the house of David, saying, “May  the Lord take vengeance on David’s enemies.” 17 And Jonathan made David swear again by his love for him, for he loved him as he loved his own soul.
18 Then Jonathan said to him, “Tomorrow is the new moon, and you will be missed, because your seat will be empty. 19 On the third day go down quickly to the place where you hid yourself when the matter was in hand, and remain beside the stone heap.  20 And I will shoot three arrows to the side of it, as though I shot at a mark. 21 And behold, I will send the young man, saying, ‘Go, find the arrows.’ If I say to the young man, ‘Look, the arrows are on this side of you, take them,’ then you are to come, for, as the Lord lives, it is safe for you and there is no danger. 22 But if I say to the youth, ‘Look, the arrows are beyond you,’ then go, for the Lord has sent you away. 23 And as for the matter of which you and I have spoken, behold, the Lord is between you and me forever.”
24 So David hid himself in the field. And when the new moon came, the king sat down to eat food. 25 The king sat on his seat, as at other times, on the seat by the wall. Jonathan sat opposite,  and Abner sat by Saul’s side, but David’s place was empty.
26 Yet Saul did not say anything that day, for he thought, “Something has happened to him. He is not clean; surely he is not clean.” 27 But on the second day, the day after the new moon, David’s place was empty. And Saul said to Jonathan his son, “Why has not the son of Jesse come to the meal, either yesterday or today?” 28 Jonathan answered Saul, “David earnestly asked leave of me to go to Bethlehem. 29 He said, ‘Let me go, for our clan holds a sacrifice in the city, and my brother has commanded me to be there. So now, if I have found favor in your eyes, let me get away and see my brothers.’ For this reason he has not come to the king’s table.”
30 Then Saul’s anger was kindled against Jonathan, and he said to him, “You son of a perverse, rebellious woman, do I not know that you have chosen the son of Jesse to your own shame, and to the shame of your mother’s nakedness? 31 For as long as the son of Jesse lives on the earth, neither you nor your kingdom shall be established. Therefore send and bring him to me, for he shall surely die.” 32 Then Jonathan answered Saul his father, “Why should he be put to death? What has he done?” 33 But Saul hurled his spear at him to strike him. So Jonathan knew that his father was determined to put David to death. 34 And Jonathan rose from the table in fierce anger and ate no food the second day of the month, for he was grieved for David, because his father had disgraced him.
35 In the morning Jonathan went out into the field to the appointment with David, and with him a little boy. 36 And he said to his boy, “Run and find the arrows that I shoot.” As the boy ran, he shot an arrow beyond him. 37 And when the boy came to the place of the arrow that Jonathan had shot, Jonathan called after the boy and said, “Is not the arrow beyond you?” 38 And Jonathan called after the boy, “Hurry! Be quick! Do not stay!” So Jonathan’s boy gathered up the arrows and came to his master. 39 But the boy knew nothing. Only Jonathan and David knew the matter. 40 And Jonathan gave his weapons to his boy and said to him, “Go and carry them to the city.” 41 And as soon as the boy had gone, David rose from beside the stone heap  and fell on his face to the ground and bowed three times. And they kissed one another and wept with one another, David weeping the most. 42 Then Jonathan said to David, “Go in peace, because we have sworn both of us in the name of the Lord, saying, ‘The Lord shall be between me and you, and between my offspring and your offspring, forever.’” And he rose and departed, and Jonathan went into the city. 
David and the Holy Bread
21:1  Then David came to Nob to Ahimelech the priest. And Ahimelech came to meet David trembling and said to him, “Why are you alone, and no one with you?” 2 And David said to Ahimelech the priest, “The king has charged me with a matter and said to me, ‘Let no one know anything of the matter about which I send you, and with which I have charged you.’ I have made an appointment with the young men for such and such a place. 3 Now then, what do you have on hand? Give me five loaves of bread, or whatever is here.” 4 And the priest answered David, “I have no common bread on hand, but there is holy bread—if the young men have kept themselves from women.” 5 And David answered the priest, “Truly women have been kept from us as always when I go on an expedition. The vessels of the young men are holy even when it is an ordinary journey. How much more today will their vessels be holy?” 6 So the priest gave him the holy bread, for there was no bread there but the bread of the Presence, which is removed from before the Lord, to be replaced by hot bread on the day it is taken away.
7 Now a certain man of the servants of Saul was there that day, detained before the Lord. His name was Doeg the Edomite, the chief of Saul’s herdsmen.
8 Then David said to Ahimelech, “Then have you not here a spear or a sword at hand? For I have brought neither my sword nor my weapons with me, because the king’s business required haste.” 9 And the priest said, “The sword of Goliath the Philistine, whom you struck down in the Valley of Elah, behold, it is here wrapped in a cloth behind the ephod. If you will take that, take it, for there is none but that here.” And David said, “There is none like that; give it to me.”
David Flees to Gath
10 And David rose and fled that day from Saul and went to Achish the king of Gath. 11 And the servants of Achish said to him, “Is not this David the king of the land? Did they not sing to one another of him in dances,
‘Saul has struck down his thousands,
and David his ten thousands’?”
12 And David took these words to heart and was much afraid of Achish the king of Gath. 13 So he changed his behavior before them and pretended to be insane in their hands and made marks on the doors of the gate and let his spittle run down his beard. 14 Then Achish said to his servants, “Behold, you see the man is mad. Why then have you brought him to me? 15 Do I lack madmen, that you have brought this fellow to behave as a madman in my presence? Shall this fellow come into my house?”
The Parable of the Prodigal Son
11 And he said, “There was a man who had two sons. 12 And the younger of them said to his father, ‘Father, give me the share of property that is coming to me.’ And he divided his property between them. 13 Not many days later, the younger son gathered all he had and took a journey into a far country, and there he squandered his property in reckless living. 14 And when he had spent everything, a severe famine arose in that country, and he began to be in need. 15 So he went and hired himself out to  one of the citizens of that country, who sent him into his fields to feed pigs.16 And he was longing to be fed with the pods that the pigs ate, and no one gave him anything.
17 “But when he came to himself, he said, ‘How many of my father’s hired servants have more than enough bread, but I perish here with hunger! 18 I will arise and go to my father, and I will say to him, “Father, I have sinned against heaven and before you. 19 I am no longer worthy to be called your son. Treat me as one of your hired servants.”’ 20 And he arose and came to his father. But while he was still a long way off, his father saw him and felt compassion, and ran and embraced him and kissed him. 21 And the son said to him, ‘Father, I have sinned against heaven and before you. I am no longer worthy to be called your son.’  22 But the father said to his servants,  ‘Bring quickly the best robe, and put it on him, and put a ring on his hand, and shoes on his feet.23 And bring the fattened calf and kill it, and let us eat and celebrate. 24 For this my son was dead, and is alive again; he was lost, and is found.’ And they began to celebrate.
25 “Now his older son was in the field, and as he came and drew near to the house, he heard music and dancing. 26 And he called one of the servants and asked what these things meant. 27 And he said to him, ‘Your brother has come, and your father has killed the fattened calf, because he has received him back safe and sound.’ 28 But he was angry and refused to go in. His father came out and entreated him, 29 but he answered his father, ‘Look, these many years I have served you, and I never disobeyed your command, yet you never gave me a young goat, that I might celebrate with my friends. 30 But when this son of yours came, who has devoured your property with prostitutes, you killed the fattened calf for him!’ 31 And he said to him, ‘Son, you are always with me, and all that is mine is yours. 32 It was fitting to celebrate and be glad, for this your brother was dead, and is alive; he was lost, and is found.’”
