Aren't we born with the sin nature? It isn't something we develope after birth, based on what, our upbringing, our surroundings? It is our nature as humans to sin. What goes against our nature is not to sin. And I know theres been so heavy discussion here in the past over whether christians continue to sin after salvation. Such as old sins revisited, stuff you struggle with, that stuff that sneaks up on you and there you go, you've sinned, that old stuff you stuill have to pray about for strength to resist temptation. I mean after all we wouldn't have temptations at all if we didn't still sin sometimes. I say all this to ask, So why are we surprised when non believers sin? We were all born with the sin nature. I'm thinking specifically of homosexuality. People born with the sin nature, sinning. What a surprise.
