What does the Bible say about the shifting cultural values of sex, relationships, and gender/identit

We live in a society where everyone thinks they’re right, everyone can find a community that believes exactly what they do, nobody needs to be challenged in their line of thinking unless they seek it out, and consequently the boundaries of what is acceptable keeps growing until seemingly nothing is off limits. As society becomes less and less Christian, we have stopped looking to God and His Word to set the standards with which we live and have allowed everyone to set for themselves what they think is right and wrong. Today, we’re going to do our best to go to scripture and see what God has to say on these very difficult topics of marriage, sex, gender, and identity.
