I’m one of those ex Christian. As much as atheists hate the word “faith”, it is actually one of the most powerful things that can lead believers “astray”. It is the belief that God is indeed all loving that it claims to. As a religious person, I didn’t have knowledge that atheists have and was discouraged to use my logic. But I strongly believed that God was good, nothing like the one that religion introduce to us. That’s how, many apostates turn away from religion. That’s why, many ex-religious used to be the most faithful and have a vast knowledge on religion.
