When Jesus described Himself as the Bread of Life, He had more than just floor, shortening and water in mind. He meant His perfect life that would fulfill all of God's commands and His precious blood that would be spilt in full payment for all sins.
The soul, famished because of sin, can feast on Jesus' payment and be filled. The soul, hungry for a perfect life to present to God in the judgement, can reach for Jesus' righteousness and be satisfied. For the hungry sinner, Jesus is not just good bread. He's the only bread.
Richard Lauersdorf, "Together With Jesus," January 15 devotion.
