Give us this day our daily bread. Matthew 6:11
Once upon a time the Lord God got the attention of a man, Moses. He introduced Himself to this man saying, “I am the God of your Father, the God of Abraham, the God of Isaac, and the God of Jacob.” (Ex 3:6) He told Moses that he had observed the misery of His people and heard their cry [because they lived under the conditions of slavery]. He was going to free them and send them to a good and broad land flowing with milk and honey. (Ex 3:7-8)
After the Lord God did what He said He would do, and these people left Egypt they became very hungry. Moses told God about their hunger. God answered, “I am going to rain bread from heaven for you, [so that] each day the people shall go out and gather enough for that day. In that way [said the Lord to Moses, He would] test them whether they would follow His instruction.” (Ex 16:4).
Free food, all you can eat, one day at a time. The deal was that they should only gather enough bread for one day. If they gathered too much it would rot. God gave them each day, their daily bread. Day-old rotten bread was evidence of faithlessness and greed.
Picture this: A winding rocky hilly trail that leads to the land of immortality, strewn with hikers, aspiring immortals, who haven't a care in the world, other than to reach the terminus ask God for their daily bread. As in the days of the great exodus, the Lord provides to sustain their mortals bodies while their souls gradually become indestructible.
Give us this day our daily bread is code for: We are your hungry people, Lord. We trust you and we will not be greedy. Try us.
