Although the legal definition of adultery differs in nearly every legal system, the common theme is sexual relations outside of marriage, in one form or another. Wikipedia
The woman caught in adultery was about to be stoned, but Jesus said to the group, “Let him who is without sin among you be the first to throw a stone at her.” Everyone walked away. But what I think we all forget is that he told her, “Neither do I condemn you; go, and from now on sin no more.” He forgave her, but told her not to sin anymore!
Everyone learned a lesson that day, the scribes and the Pharisees because none of them were without sin, but also the one caught in the sin, the woman. He wanted her to change her behavior.
Tread carefully my friends. We’re all sinners, but don’t get so upset with those who are trying to snatch you from the fire of hell. If you’re a man that wants to dress like a woman, or a woman that wants to dress like a man, you go ahead and do your thing (though the Bible says not to do that either, but the lines are quite blurred with the current styles), but don’t let it cross over into sin by having sexual relations outside of the Biblical definition of marriage, which is between a biological man and a biological woman.
If you’re a Christian and trying to help snatch someone from the fire, make sure you are doing it with love, and not hateful speech.
And then there is this, the reason why it’s important:
He who commits adultery lacks sense; he who does it destroys himself. He will get wounds and dishonor, and his disgrace will not be wiped away. Proverbs 6:32-33
