Because all five versions of Jesus ─ Paul's, Mark's, Matthew's, Luke's and John's ─ never once claim to be God, and instead expressly deny that they're God ─ as a sample, try:
Paul, 1 Corinthians 8: 6 yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist.
Paul, Philippians 2: 11 and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.
Mark 12: 29 Jesus answered, “The first is, ‘Hear, O Israel: The Lord our God, the Lord is one;” ... 32 And the scribe said to him, “You are right, Teacher; you have truly said that he is one, and there is no other but he;
Matthew 20:23 “to sit at my right hand and at my left is not mine to grant, but it is for those for whom it has been prepared by my Father.”
Luke 18:19 “Why do you call me good? No one is good but God alone.”
John 5:19 “the Son can do nothing of his own accord, but only what he sees the Father doing”
John 8:42 “I proceeded and came forth from God; I came not of my own accord, but he sent me.”
John 10:29 “My Father [...] is greater than all”.
John 14:28 [...] I go to the Father; for the Father is greater than I.
John 17:3 “And this is eternal life, that they know thee the only true God, and Jesus Christ whom thou hast sent.”
John 20:17 “I am ascending to my Father and your Father, to my God and your God.”
And there are more where those came from.
Of course, you're free to believe that Jesus is God if you wish; but I don't see how you can say the NT supports that view. Bear in mind that neither Jesus nor his followers had ever heard of the Trinity doctrine, which wasn't invented till the 4th century CE.
