Let’s start with an antithesis. On the one hand, God dwells everywhere. Nothing could exist at all if it were not upheld immediately by God’s power. On the other hand: We cannot see; we cannot grasp; we cannot know God.
See? Antithesis. Both true. God everywhere. But everything we see, know, conceive: not God. Human beings search constantly for God, Who is everywhere.
Then: God began to work with us to help us deal with this problem. He drew close to the ancient Israelites. He gave them His holy name to invoke. He led them out of slavery to their homeland. He established a dwelling place with them. The Ark of the Covenant.
Like all the chapters of all the gospels, the sixth chapter of John proclaims that the Messiah has come, and it is Jesus.
It will help us to understand this chapter if we recall some of the great deeds the Lord did through His prophet Moses in ancient times. Through Moses, the Lord taught His people a lot about how to hope for the Messiah—about how to hope for freedom and salvation.
Let us recall the Exodus of the Israelites. By the power of God, Moses brought plagues upon the Egyptian slave-masters. Then he parted the Red Sea and led the people across it. Later, Moses turned the desert rock into a spring of water.
Moses also demonstrated the power of God when he brought the Law down from Mt. Sinai and then consecrated the people in a covenant of obedience to it.
