I had a long & sometimes heated discussion on another site with a gent who insisted that, since God is a Spirit, He has no body. I kept repeating SCRIPTURAL PROOF that He DOES have a body when He desires. That Spiritual proof is:
Exodus 33:20 But He said, “You cannot see My face; for no man shall see Me, and live.” 21 And the Lord said, “Here is a place by Me, and you shall stand on the rock. 22 So it shall be, while My glory passes by, that I will put you in the cleft of the rock, and will cover you with My hand while I pass by. 23 Then I will take away My hand, and you shall see My back; but My face shall not be seen.”
Pretty positive proof that God does indeed have a body when He chooses. So, we are made in the image (not the SUBSTANCE) of God's body. After all, He said, "Let US make man in OUR image, after OUR likeness."
And, of course, He can assume any form He chooses, whenever He chooses. The Holy Spirit assumed the form pof a dove at Jesus' baptism.
