Colossians 1:14 In whom we have redemption through his blood, even the forgiveness of sins: 15 Who is the image of the invisible God, the firstborn of every creature: 16 For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: The use of the invisible God in the Bible is meaning the unseen God the Father. The Son of God being the image of the invisible God means God the Father has a similar image that can be seen too, but not presently. "Invisible God" does not mean that the Father does not have a celestial body. It just means at that moment, He is not being seen by mankind. Jesus has ascended to the right hand of God the Father, and so He is "invisible" to us now as One that cannot be seen at this present time. 1 Timothy 1:17Now unto the King eternal, immortal, invisible, the only wise God, be honour and glory for ever and ever. Amen. So the use of invisible God in the Bible does not mean God does not have a body because God did asked for creating us in their image. Genesis 1: 26 And God said, Let us make man in our image, after our likeness:.... So if anyone asks what the invisible God looks like and what image He has, tell them to look at Jesus Christ as He is the image of the invisible God.
