You’re joking right? Not a very big deal? I’m not even going down this road, from Genesis to Revelation, God has spoken about sin. It was such a “big deal” in fact, that God sent His only begotten Son to die for our sin. Please don’t tell me that I don’t think it’s really a very big deal. It cost Christ everything.

Yeah, I'm joking, because actually the Bible does say a great deal about sin. (But nothing about a "sin nature".)

It never says all sins are equal to God, and it never says your own personal sins don't matter, though. They aren't (1 John says so), and they matter a great deal.
