Paul proclaims a lost truth. God is a physical personage, he is known (or can be known) to us. In Acts 17: 23, Paul proclaims to the people of Athens (who worshiped idols and an Unknown God) “him declare I unto you.” God is not impersonal, he is not invisible, insofar as we seek him. He wants us to know him, the same way that Moses did, face to face.
God is also a personage of physical proportions. He has a tangible body. Paul declares in Acts 17: 28-29, that we are the offspring of God. He is the creator of our spiritual beings, our earthly parents are the creators of the physical bodies that house our spirits.
