The first words of John's gospel imply that Jesus ("the Word") is God.
In the beginning was the Word, and the Word was with God, and
the Word was God. John 1:1
And the Word was made flesh, and dwelt among us. John 1:14
And Jesus (sometimes) claimed to be God.
By forgiving sins. (Only God can forgive sins.)
Jesus ... said unto the sick of the palsy; Son, be of good cheer; thy sins be forgiven thee. And, behold, certain of the scribes said within themselves, This man blasphemeth
... That ye may know that the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,)
Arise, take up thy bed, and go unto thine house. Matthew 9:2-6, Mark 2:3-12
Therefore did the Jews persecute Jesus, and sought to slay him, because he had done these things on the sabbath day.
But Jesus answered them, My Father worketh hitherto, and I work. Therefore the Jews sought the more to kill him, because
he not only had broken the sabbath, but said also that God was his Father, making himself equal with God. John 5:16-18
He that hath seen me hath seen the Father. John 14:9
By saying that he existed before Abraham, using one of God's names, "I am."
Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am. John 8:58
After hearing Jesus say these things, the Jews tried to stone him to death for claiming to be God.
I and my Father are one. Then the Jews took up stones again to stone him. John 10:30-31
The Father is in me, and I in him. Therefore they sought again to take him. John 10:38-39
And when Thomas called Jesus God, Jesus didn't correct him. Rather, he said that everyone should believe he is God, even those who have never seen him.
And Thomas answered and said unto him, My LORD and my God.
Jesus saith unto him, Thomas, because thou hast seen me, thou hast believed: blessed are they that have not seen,
and yet have believed. John 20:28-29
The New Testament (sometimes) also refers to Jesus as God.
That the church of God was purchased with the blood of God (or maybe the Holy Ghost).
Take heed therefore unto yourselves, and to all the flock, over the which
the Holy Ghost hath made you overseers, to feed the church of God, which he
hath purchased with his own blood. Acts 20:28
Jesus is the man God chose to judge other men and be their mediator.
Because he hath appointed a day, in the which he will judge
the world in righteousness by that man whom he hath ordained;
whereof he hath given assurance unto all men, in that he hath raised
him from the dead. Acts 17:31
For there is one God, and one mediator between God and men, the
man Christ Jesus. 1 Timothy 2:5
But he is still subject to God.
And when all things shall be subdued unto him, then shall the Son also himself be subject
unto him that put all things under him, that God may be all in all. 1 Corinthians 15:28
And although his head is God, the rest of him is human.
