"There's quite a lot on TV just now about Jesus. I'm not sure anymore....Was he the son of God, or just generally a good person?"
...or did he even exist?
Many years ago I wrestled with the same conundrums you are facing today. Is God real or true? To answer that question, you must look at the cold facts. You must shun "Divine Revelation", ignore wishful thinking, and avoid the opinions of those around you and concentrate on the evidence.
What I personally found was that God supposedly gave us five senses with which to perceive the world. Yet with none of these senses can we perceive God. We cannot taste to see that he is good. We cannot see him or feel him or smell him because he is incorporeal. We cannot hear him because he does not speak. We pray to him but he doesn't answer. He does nothing to alleviate human suffering.
To paraphrase Carl Sagan, whats the difference between an invisible, incorporeal God who does nothing and says nothing--and no God at all?
What's "real and true" is out there, but you have to find it.
