Christ does with the five loaves and two fishes what he will later do with the bread and wine at the Last Supper. He takes the bread, gives thanks to God for it, breaks it, and distributes it. When we bless God for what we have, he gives it back to us blessed. Christ sacrificed his life for us. When we surrender our lives to him, he gives us his life to live from.
Obedient faith has miraculous issue.
