Jesus declares He is God

Another Scripture for our Jehovah Witness brethren, so that they may know we seek to follow Scripture by worshiping Jesus as God.

In John's Gospel, Jesus confirms that He is God, in among other verses, Jn9:35-39.

35. Dost thou believe in the Son of God?
36. He answered, and said: Who is he, Lord, that I may believe in him?
37. And Jesus said to him: Thou hast both seen him; and it is he that talketh with thee.
38. And he said: I believe, Lord. And falling down, he adored him.
39. And Jesus said: For judgment I am come into this world

Adoration, as well as Judgement, was always reserved for God alone in the Jewish Covenant.
The Athanasian Creed so asserts this belief: "The Father is God, the Son is God and the Holy Spirit is God"
