The first murder in recorded history was when Cain killed his brother, Abel. This came about after Cain had brought the work of his own hands as a sacrifice to God, and Abel brought a blood sacrifice, as we assume he had been instructed to do. Cain, like so many others down through history, misplaced his faith. He placed his faith in what he, himself, was able to do, rather than in God’s provision. Some years ago, I was in the home of some people, and I noticed above the baby bed, there was a sock nailed to the ceiling and it was obvious that there was something in it. When I asked about it, I was told that there was an egg in the sock and that it had been placed there to help the baby cut his teeth! Now, I would hope that sounds as crazy to you as it does to me, but it I would imagine any of the things in which we put our trust, other than that which God has instructed us to trust, looks equally absurd to God. In order not to be misplaced, faith must be connected to that which God has revealed.
