I don't really think about him very much to be honest. I'm fairly sure I believe that he wasn't the son of God, but I know there's quite a lot of evidence to suggest that a man kind of fitting his description existed all those years ago, and I'm sure he was a good guy. I think the 'miracles' he performed were probably a lot less like magic tricks (walking on water and the like) and a lot more like getting enemies to get along or giving food to the poor. I think the things he did have probably been exaggerated in the art of good story-telling and as an attempt to get people to do good things. Obviously that's just my opinion, and I would want in no way to force it on others, and I am completely respectful of the opinions of others. I think there's no way to prove it so I think it's a great topic to discuss but a silly one to argue about.
I actually read a blurb of a book whilst in a book shop today and I thought I'd share part of it here because it also kind of answers your question, (I hope you don't mind!) The book is called the Liar's Gospel by Naomi Alderman and it really made me go 'oooh, controversial!' haha
This is the story of a Jewish man, Yehoshuah, who wandered Roman-occupied Judea giving sermons and healing the sick. Now, a year after his death, four people tell their stories. His mother alternates between grief and rage while trouble brews between her village and the occupying soldiers. Iehuda, who was once Yehoshuah’s friend, recalls how he came to lose his faith and find a place among the Romans. Caiaphas, the High Priest at the great Temple in Jerusalem, tries to hold the peace between Rome and Judea. Bar-avo, a rebel and a murderer, strives to bring the peace tumbling down.
And in the midst of all of that, one inconsequential preacher died. And either something miraculous happened, or someone lied.
