For Atheists Only

I would like to ask a big favor. Forget (for a moment) about whether or not God exists, and give me your serious thoughts on the few verses below. Please read them carefully:

“Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life. Most assuredly, I say to you, the hour is coming, and now is, when the dead will hear the voice of the Son of God; and those who hear will live. For as the Father has life in Himself, so He has granted the Son to have life in Himself, and has given Him authority to execute judgment also, because He is the Son of Man. Do not marvel at this; for the hour is coming in which all who are in the graves will hear His voice and come forth—those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of condemnation” (John 5:24-29).

Here's the build-up to my question: Some say Jesus of Nazareth was a great teacher. Others say that He was crazy, while others (a few) think that He didn’t exist at all.

I think that "great" teachers don’t say the sort of weird things He said (believe His words and you have everlasting life, that His voice would raise the billions of the dead human race, etc.), and if He didn’t exist, who said these amazing words? So, I think that there are only two reasonable options. He was either a crazy liar, or He was the Son of God. Am I wrong?
