John is quite clear in his gospel that Jesus the Son is equal to God the Father.
"18 This was why the Jews were seeking all the more to kill him, because not only was he breaking the Sabbath, but he was even calling God his own Father, making himself equal with God." John :18
So the Jews actually wanted to kill Jesus for making himself equal with God. If Jesus was truly God, then he would not have corrected the Jews. If he was some kind of lesser "god" he would have stopped a lot of trouble for himself by merely saying, "Hey, you have me wrong, I am not equal to God the Father." But he did not! John is very clear to point out that the Pharisees were after Jesus for two reasons:
1. Breaking the Sabbath (really the manmade laws!)
2. Making himself equal with God.
Of course, there is the rest of John which upholds the view that Jesus is equal with God, and of course, the rest of the New Testament.
In Revelation, John calls Jesus the "Alpha and Omega" which he applies equally to the Father.
"8 “I am the Alpha and the Omega,” says the Lord God, “who is and who was and who is to come, the Almighty.” Rev. 1:8
In Greek the words LORD God are κύριος, ὁ θεός, where kurios replaces the holy tetragram YHWH יהוה which is the name of the Father in the Masoretic Old Testament. The Septuagint uses kurios for the name of God. Really, the Hebrews never used the Holy Tetragram, but substitued the name "Adonai" for the name of God. So, if you do text comparisons, there is no New Testament text that uses the Hebrew Holy Name. And Jehovah is just a bad German translation of YHWH.
Jesus is also referred to by the same title, the Alpha and the Omega. In the end of Revelation, it is Jesus talking to John.
"I am the Alpha and the Omega, the first and the last, the beginning and the end.” Rev. 22:13
As far as a good New Testament Greek bible, I use the UBS or United Bible Societies. It is good because it cites every variation in every known early manuscript. The New World translation is a joke, a beginning Bible language student could do a better job of translating than the NWT.
Very simple theology the Trinity, really. Much better than the polytheistic JW's with a greater god and a lesser god. That is heretical and does not reflect anything in the Biblical text.
