Note: Incidentally, this is also a subtle proof for weekly communion.
Food reveals the nature of God. God is a God of abundance. He is a provider. But food also reveals the nature of man. Even the smallest infant knows instinctively that food is life, and the creation account shows that even unfallen Adam had to eat. The Lord’s Table is a continual reminder that we are a needy people. Were we not needy, God would rarely if ever provide this table for us, but since we are needy, He provides it weekly, and we partake of it gladly.
