Genesis 22:1-2 is a passage that tests our faith almost as much the hero of the passage (Abraham). Abraham is asked to do the unthinkable, kill his son for God. Even more difficult to reconcile is the fact that God had also revealed that Abraham's son would one day be the start of a very large family. Somehow Abraham was able to trust God ins spite of the seemingly contradictory ideas and proved himself a man of faith. How do you handle difficult requests from God?
It's important to note the story goes on to say that God did not ask that Abraham kill his son, but that He, God, provided an alternative. In the New Testament, we see God giving His Son and ending the practice sacrifice. In the place of burnt offerings, People of faith are now called on to provide help and comfort to others as a way demonstrating devotion to God.
