The
whole of Scripture. You see, when you're speaking with a Christian, Scripture is not some old dusty book; it's a
living force.
This rational / logical element is how I came to the Lord. I was actually looking to excuse myself for not living up to what I knew is what he expected of me, hoping to find some loophole in the Bible, somewhere. Instead I found He is perfect, and fell in Love with Him. No, I'm not gay
But this one point really zeros in on the OP! We don't posit that the man Jesus was present at creation. He was born as a baby, long afterwards. What we wind up with is what has come to be termed as "the pre-incarnate Christ." I think it's important to ignore all the man-made stuff and seek G-d in earnest, for yourself. He'll show you His Truth! After that, you realize people's debates are silly and inconsequential by comparison. And that becomes the "broom" with which we can sweep away our own doubts, moment by moment.
