Jesus has a God who is his Father, Jehovah. (2 Cor. 1:3; Eph 1:3; Col 1:3; Mark 15:34; John 17:1-3; etc.) Also, even in heaven, Jesus refers to his God and the name of his God. (Rev. 3:12) Jesus cannot BE God if he is talking about God as a separate person.
Nowhere in scripture can it be found that the Father has a God. That is because Jesus himself said that the Father is "the only true God". (John 17:1-3)
The Bible clearly shows that Jesus is God's Son...not God Himself. But rather than using the entire Bible as context, many who believe that Jesus is God rely on a few selected, so-called 'proof-texts' which do not hold up under closer scrutiny:
