In studying the presences of God, I have come to notice something: when God makes his presence known, it tends to be to those who are called, set apart, or sent on a mission.
God appeared to Abraham, the first of the called or chosen people that would become Israel.
God appeared to Jacob, ancestor of all the people of Israel. His life was not his own.
God appeared to Moses in the burning bush, and Moses was sent back to Egypt. Even though he went grudgingly, he did great things. God had made himself known to Moses, and Moses had a mission.
When Moses led the people out of Egypt, God appeared to all of Israel in the cloud, in the fire, and again at Mt. Sinai where he had shown himself to Moses before. He made his presence known in the Tabernacle, then in the Temple, as the entire nation was set apart for God.
It seems like ripples in a pond as the call of God goes in ever-wider circles, as God's presence in the world becomes more enduring and gives rise to more knowledge of the Holy One.
Then "the word became flesh and tabernacled among us." The boundaries were removed on who could see God, who could know God. The call went out to all the earth.
