We are told not to judge. Paul said, WHAT DO I HAVE TO DO IN JUDGING UNBELIEVERS? That's God's job. We only judge those inside, not outside, the family of believers.
You can quote Jeremiah, Habakkuk, Obadiah, Philemon.... but when it comes down to it, we're not here to judge the unsaved world. That's God's job. We're here to bring them to Him in love. These sorts of religious debates don't generally do that. They only create a WIDER wedge. That's why God said, DON'T JUDGE. Too bad more Christians won't get that, and listen to Paul. For the unbeliever, tell them about the glorious Gospel, not beating them over the head with your morality
Kind of puts the cabash on your weak case.
Anything else you have in mind while I'm here?
