(Colossians 1:15) He is the image of the invisible God, the firstborn of all creation;
You can see the invisible God but what you cannot do is to tell others how he looks like.
------------------
That's right. Because God a spirit person, not a physical person, he cannot be described in physical terms. However it is possible to come to know and reflect his personality.
(Colossians 3:10) and clothe yourselves with the new personality, which through accurate knowledge is being made new according to the image of the One who created it,
MrG (Colossians 1:15) is referring to Jesus, if God is Spirit and Jesus is the image of the invisible God what is it telling you about Jesus
Oh, you answered it, Jesus is reflecting God's image in your “However it is possible to come to know and reflect his personality.”
John 14:9 Jesus answered: “Don’t you know me, Philip, even after I have been among you such a long time? Anyone who has seen me has seen the Father. How can you say, ‘Show us the Father’?
If Jesus is just a created being, then so is God, as Jesus is in God's image.
