Joshua has a great point. If one says that homosexuality is not a sin, then where is the line drawn? That was what I meant when I said opening the wrong doors is not wise. This is why we have the Word of God, because it gives us a clear understanding of what is right and wrong. Just as Adam and Eve ate of the Tree of the Knowledge of Good and Evil and realized their nakedness, so the Bible and its teachings gives us that knowledge. The church in Paul’s time did not tolerate sin in the church. Why should we be tolerant? Just because the "world" tolerates it? We need to stop being afraid to speak the truth. The great martyrs in the Bible were not afraid. The reason why we should not accept homosexuality is because we should love people and want them to have eternal life with the Lord Jesus Christ. We  cannot change a person’s mind and heart, only the Spirit can. All we can do is be a guide to those who do not understand.
