Upon one’s conversion to Christ, habitual sin of fornication should cease. It did for me. And “I” had nothing to “do with it”, being too afraid to commit to actually making changes in my life so dramatic. At a certain point after agonizing about this and other aspects of being a believer in Christ, my change in attitude just happened, and was quite beyond my control. Scripture suddenly became simpler, clearer - and something I looked forward to with delight rather than anxiety.
Any time we see habitual grave sins (in ourselves or others), it should “ring a bell” in our mind. We should see that the person is not living according to the Word of God.
Repentence is obviously needed.
Yes, there will always be some sin in the lives of true believers - true believers are NOT perfect. But if we find ourselves committing grave sins... especially habitually... that bell should be going off in our mind, we should feel a dire need to repent - and repentence involves not only admitting the sin is a sin, admitting that we did it, but also committing to “go and sin no more”. And we should find ourselves having success at that, for that particular sin.
The Book of Romans is, of course, an excellent guide on this subject.
I am fully supportive of marriage. I’m not here to undercut it. I do not approve of people living together before marriage. I’ve never done it myself.
In the last twenty-five years, I have been with one woman. It was my wife. She has been gone for going on two years. I’m not compelled to sleep with someone else.
I am very familiar with the Bible. I am familiar with the verses. I am also able to think for myself, and there are parts of the Bible I don’t take literally.
To me the decision to be with one person doesn’t happen on the day you say I do. It takes place when you decide that you will say I do, and with incredible happiness.
So do I think that if a woman and a man have sex 48 hours before they are officially married, they are going to rot in hell for all of eternity? No.
You can scrape up every Bible verse you can find, I’m still not going to buy into the idea that God will curse you forever because after a 50 year marriage full of joy and love and friendship, you had sex 48 hours too early.
Now maybe that makes me a heathen. To me it makes me a person that understands God loves us and knows what is in our hearts.
