what is the opposite english word for "Sin" ? [Spirituality & Religion]

I feel there is no word to say antonym of "Sin".
There are various perspective for "Sin" according to each religion. "Sin" differes from religion to religion.

I am not talking about only GODS. Because some religion leaders are not GODS. For a example lord buddha is a human.

So i would like to find the opposite word of "Sin" in English language
