This entry gives several parings of scripture from the New World Translation that are used to show that the NWT, despite its many changes and distortions, still shows Jesus to be God and the Holy Spirit to be a personhood of God. These scriptures can be viewed/demonstrated on JW.org and would be good to know if the opportunity for conversation with a Jehovah's Witness arises.
The Gospel of John is a great starting place when looking for confirmation of the Deity of Jesus, who, in a fashion beyond our understanding, is not only God, but is the one God along with the Father and the Holy Spirit. This essay looks at deity throughout John's gospel, and highlights places where the New World Translation has misconstrued the text to salvage their doctrines. In smaller part, the deity and personhood of the Holy Spirit is discovered as well.
This article discusses the similarities between the teaching of the Jehovah's Witnesses that Jesus is not God to the "little gods" heresy of some prosperity preachers today. These two derivations from scripture have similar roots, and both errors share some fundamental misunderstands from scripture.
William I. Cetnar's "wheel of deity" is reviewed regarding the biblical texts declarations that both God the Father and Jesus the Son are in fact, the one true God. The fullness of deity is applied to both in scripture, yet Christianity is a monotheistic religion. While difficult to explain, the clarity of scripture is absolute.

He's proclaiming his deity by using the very name of God that God proclaimed of himself in Exodus 3:14, when God said to Moses "I AM WHO I AM... Say this to the people of Israel, ‘I AM has sent me to you.’”
