Hi. For the person calling people stupid have a look at yourself first, there is no reason to judge someone because they are searching for truth, in fact if anything that should make you think more of them. You will find it isn't stupid at all to ask where Jesus said He was God, because if you've ever argued the point with a mormon of J.W then you'll find they've got unique ways of looking at things which makes it very hard to prove a point. Sorry I don't have verses and chapters handy, unlike some I can never remember verses and chapter numbers.
There are a few things to get straight first, either Jesus is God or a lunatic. There is no 'great teacher' classification, either He listened to voices in His head and was crazy enough to die due to them, dying in such a way that a sain person would have avoided. Teachers don't die for their teachings, they aren't worth dying for unless they are devine, in which case Jesus was God, because that is what He taught. Where though???
Jesus is called Lord a lot, however in the New Testament He isn't called Yahweh, which means God. Thomas does call Him 'my Lord and my God' in John, but because Thomas wasn't Jesus, Jehovah Witness's say Thomas was mistaken, he was only a man. Jesus didn't say, you're right, or you're wrong, so it's really your preconcieved idea of Jesus which gives you your point of view out of this one. An interesting observation is however, that God the Father was called Lord half the time in the Old Testament, Jesus was called Lord all the time in the New Testament. Jehovah Witness's don't like this point. Jesus also says 'before the world was made I am'. J.W change it to 'I was' to get out of this, the translation is very biased obviously to prove the J.W's point, interpretation rules come to the conclusion the 'I am' is the best translation, but lets not get into interpretation I haven't studied ancient greek and hebrew yet. But the reaction of the Pharasies poves the point that Jesus was claiming to be God because God in the Old Testament calls Himself the 'I am'. This is because the Pharasies proceeded to try to stone Jesus to kill Him, and what is judge as worthy of death in Ancient Jewish Law? Blasphemy, that is what they judged Jesus as claiming, that He was God, therefore they judged by their Law that they should kill Him. J.W's say Jesus just pushed them too far, which of course is there point of view because they want it to be. The only real way of proving Jesus was God according to the Bible is finding somewhere in the Bible where Jesus is said to be Yahweh by God Himself. So where is this written? Remeber He can't be called Lord, even though God the Father is called Lord in the Old Testament, He must be called Yahweh! You'll find this in only one place, a place which the J.W's have missed and have actually translated properly, Isiah chapter 40 (I think, popular verse anyway you'll find it) Isiah the Prophet speaking the words of God the Father Himself, said "And there will be a voice comming from the desert, prepare the way for God" The original language says prepare the way for Yahweh, John the Baptist was the voice in the desert preparing the way for who? Jesus! So Jesus is called GOD Yahweh. Pretty convincing if you believe the Bible, which is a whole other topic. ALso remember Jesus always wanted to Glorify His father, so He always put the emphasis on Him, the Father is the Head of the Trinity. Jesus was also a man at the time, and when He says things like 'I don't know when the Last days will be', it is because He gave up much of His devine nature when He came down to Earth as a man. He had to or else He wouldn't have been human now would He? Very hard to understand, but He is God and God is a lot more complicated then us humans and we don't even understand ourselves half the Time. One more thing. The Trinity God the Father, The Son, The Holy Spirit. The Father is the Head, He decides what to do, the Son is God but He goes along with the Fathers will, and the Holy Spirit does the Will of the Father as well. This relationship is like this in order to function. You can't have the Father wanting to turn right, the Son wanting to turn left, and the Spirit wanting to go back. Function in Unity dictates authority. The Son isn't anything less for doing the will of the Father, and neither the Spirit, they simply have different functions in the same entity. Confusing hey! But show me an ant that can understand a space shuttle, and I'll be able to show you a man who can understand God.
Hope that helps a bit.
