To summarize, Jesus took the penalty of the law and we no longer need to follow it. But what Paul says in Romans is right on when he says that we should no longer continue sinning just because we are freed from it. As we search out whether homosexuality is a moral sin, and not just a piece of law, we find that it is. Therefore, we should not live a life of homosexuality for it is a sin. This is exactly what the death of Jesus set us free from, sin.
