I have converted to Christianity

[Ace Otana]

I do not reject atheism

Atheism simply means 'without' theism.

Christianity makes more sense of the world than any other perceptual framework.

And has absolutely no explanatory power. Did you know that? Also it doesn't explain how anything works. How things came to be. It explains nothing.

I have come to the conclusion that unconditional love is the key to everything. Explaining emotions by immensely complex neural biochemical reactions in the brain does not even come close to the profound subjective experience of such.

You don't like the fact that emotions are caused entirely by chemical reactions so you reject it and go for a more pleasant (more desirable) yet unrealistic explanation. That is irrational.

For instance, arrogantly asserting that spiritual individuals are delusional/hallucinating; it is such a simplistic explanation for an enormously complex situation

You're supposed to stick to simple explanations until there is evidence for the complex. It's not just Occam's razer, it's logical procedure.
Simple explanations are far more likely to be correct than more complex ones.

Perhaps you are meant for religion after all....

Some people need religion because when they don't have an explanation for something they will go crazy, whereas god fills that void. As long as you are only using to help yourself and not to preach to anyone or try to convert anyone, more power to you.

It fills the void but not with knowledge. Just a baseless assumption. Better off putting a question mark there instead, at least that way you're being honest about it.
