God in the New Testament

The disciples knew of only one God.

1 Corinthians 8:4-6 Hence, as to the eating of food offered to idols, we know that "an idol has no real existence," and that "there is no God but one." For although there may be so-called gods in heaven or on earth-as indeed there are many "gods" and many "lords"- 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.

Did they say "one God, the Son"? No! Did they say "one God, the Holy Spirit"? No! Did they say "one God, the Trinity"? No! They said "one God, the Father." Period!

Romans 15:6 that together you may with one voice glorify the God and Father of our Lord Jesus Christ.

1 Timothy 1:2 To Timothy, my true child in the faith: Grace, mercy, and peace from God the Father and Christ Jesus our Lord.

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 Jesus said to her, "Do not hold me, for I have not yet ascended to the Father; but go to my brethren and say to them, I am ascending to my Father and your Father, to my God and your God."

KJV:

"That ye may be the children of your Father which is in heaven..." Matthew 5:45

"Be ye therefore perfect, even as your Father which is in heaven is perfect." Matthew 5:48:

"and I (God) will receive you, And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty." 2 Corinthians 6:17-18

Please also read 2 Corinthians 11:31, Ephesians 1:3, Ephesians 1:17, and 1 Peter 1:3 for similar affirmations of Jesus having a God.
