Man fell through the indulgence of appetite. God had given him all the trees that were 'good for food' Genesis 2:9. He did not need to eat of the tree of knowledge. In the work of redemption Jesus began just where man had fallen. It was in order to break the power of appetite that He fasted for forty days. Jesus would not have been tried on this point if man would not face a similar temptation. Man can gain immortality only by overcoming as Christ overcame.
