Hebrews 2:1 tells us that “we must pay much closer attention to what we have heard, lest we drift away from it.” Much like a leisurely float down a meandering river, if we choose to relax in the Christian life we can be assured that the tide of our culture and the tug of our flesh will draw our hearts and minds away from God’s truth and further down the stream of unbelief and compromise.
The world we live in and the bodies we are encased in are not neutral. They persistently and actively work against the desires of our regenerate hearts and the righteous convictions of God’s Spirit. This is why the Bible says to “present your bodies as living sacrifices, holy and acceptable to God” and to “not be conformed to this world, but be transformed by the renewal of your mind” (Rom.12:1-2). This is an active, focused, thoughtful work to “pay close attention” to God’s truth. And it is needful because your regenerate heart is designed to be continually “renewed in knowledge after the image of its creator” (Col.3:10).
So with your full “attention” dive back into the life-changing “knowledge” you find in God’s word and allow your mind to be “renewed”, so that “by testing you may discern what is the will of God, what is good and acceptable and perfect” (Rom.12:2).
