Is pre-marital shaggin even a sin anymore?

Is it still a sin? Yes. Do most Christians actually wait until marriage? No. That doesn't make it right. Some Christians just want to follow the parts of the Bible that doesn't put too many restrictions on them. God doesn't expect perfection out of Christians, which is a good thing. Speaking as a Christian, I can tell you that being a Christian doesn't give you an "I'm perfect" badge. Nor does it give you a free p to do whatever you want just because you've been forgiven. Although I think some Christians forget that, which is why so many people have a bad opinion of Christians. Like I said, God doesn't expect perfection (because we're humans), but He does expect us to try and follow his guidlines (The Bible) as closely as possible (which means not picking and choosing what you want to do or what you don't) Hope this helps you....good luck and God bless.
