God detests fornication and adultery…the Bible is resoundingly clear on that. Even in the New Covenant, Paul, speaking to believers about believers, says that fornicators will not inherit the kingdom of heaven. He had a direct revelation of the God-man Jesus Christ Resurrected–so this is divine revelation, not mere shifting sands of human opinion.
Our society is abnormal; the sinfulness and/or illicitness of fornication and adultery is a universal feature of human cultures. This moral law is obvious through natural law.
It takes continuing conversion so see things as God sees them, especially in our corrupt culture that has crazily strayed so far from God’s ways.
Sin, especially habitual sin, darkens the intellect and compromises the will. You will not know the damage of your sin until the unfolding of your whole life, and perhaps not deeply and fully and clearly until the next life.
So–if you did what was right, are you going to teach your children to fornicate freely no matter what God says? That is failing in your first duty as a parent–doing your best to get your children to heaven.
And I pose my favorite Bible pop quiz once again: when in the Bible, it says, “They did what was right in their own eyes,” is that a good thing or a bad thing? Look it up and read it in context and you will have your answer.
It took me years to be deeply converted and scrubbed clean of my sins, and I am not done yet–God is till working on me. Sometimes it feels like a Silkwood shower!

So I am preaching primarily to myself here, since I am the most miserable of unworthy sinners.
