Who is God?

For in Christ lives all the fullness of God in a human body. Colossians 2:9

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'? John 14:9 For when you see me, you are seeing the one who sent me. John 12:45 No one has ever seen God, but God the One and Only, who is at the Father's side, has made him known.John 1:18
