Saying that love must be a part of the universe because you had to come to know it some how is a non-starter. That line of reasoning can be applied equally to anything you know that are also human constructs. Did God make hate into the fabric of the universe? Is the English Language part of the universe? What about Post modern Art? How did anyone come to know sadness if it isn't part of the universe? These things aren't found in the universe, they are found in us. They are human constructs. Some are evolutionary, others are emergent properties of our evolution. But they are woven into the universe. The universe is a vast amoral expanse which is overwhelmingly hostile to life.
Claiming parasites are a result of evolution doesn't get god off the hook. John Haught, as I mentioned before, has come up with some bizarre and twisted theology to try and explain why god would set into motion something he would know full well from the outset would create a world of horrors that belongs in some cosmic circus side show. If you believe in a creator god, then he is responsible for the eons of pain, fear, and violence that he beset on the concept he called "life."
So if a cold amoral universe, and a violent diseased planet, and the bible having been shown to be a set of fanciful myths no different from greek or roman mythology, and you still think "well, there are answers, we just don't know them." Is there anything that you could know that would convince you that your world view is wrong? How much would it take? Another holocaust? The near eradication of mankind by natural forces? Alien invasion? Or is it a matter of "It doesn't matter what happens, It's jesus or bust, I'll just work around reality as I need to?" That is something I had to ask myself when I was still a witness. With platitudes like "don't lean on your own understanding" and "the light get's brighter" I could answer just about any theological or scientific question with a mere shrug and that was enough. Is that really enough?
