When I was trying to fashion my own gentler kinder god, I was looking for a more believable god. I hoped this would give me the faith to be a better Christian. But there was no more evidence for my personal god than there was for the Bible God, either the New Testament God or the Old.
The existence of a guy named Jesus, is pretty well accepted by most Bible Scholars, although they do have a dog in that race. But it's likely a guy named Jesus existed if the name was as popular back then as it is now, but the Bible Jesus walked on water, and I'm pretty sure that guy didn't exist. Whether there was a preacher sort is also debatable, because there are no secular records of such a major personality and leader of people that mirror any of the comings and goings of Bible Jesus. Maybe one existed, but other than popular opinion, I don't see any real evidence that would lock that idea down for me. The New Testament describes such a person, but the new testament reads much like Homer's Illiad, filled with the same magical mythological sounding stories, and it's the only written material about a guy named Jesus who is the center of Christian dogma.
