Pre-marital sex is wrong in the eyes of the lord. I've already broken this law. But I would like to redeem my walk in the true law. So if sex is wrong out of wed-lock, then what is okay? Is kissing wrong? Touching? Sharing a bed to sleep on? What about temptation? If temptation draws you near sin, I would assume you should stay clear out of its way, but is it wrong to let the tempter tempt you at all? How do you know when you begin, are about to begin, or have already committed adultery in the eyes of God? Will you hear/see/feel/sense it, know it, or commit to the mistake unknowingly? I have heard that while you may not touch any female, if you look on them in a lustful manner, then you have committed adultery in your heart. What about punishment? How will one know, unmistakably, where their vile acts have led them to? Is hell the only punishment, or just a consequence to our fallacy? I think as long as we are still here, on Earth, we have a chance to turn it around.
I always tell people it depends on conviction. Paul talks about the fact that some people cannot handle alcohol, and thus shouldn't drink it nor go near it. But some people can handle alcohol and are free to enjoy it, to the Glory of God. Explicitly and obviously
sex outside marriage is a sin. As for the other things you mentioned, some people can handle kissing, and some people cannot. Some people can handle hugging, some cannot.
In your case, I would suggest you steer very clear of any and everything you mentioned. I just don't know that you're mature enough Spiritually. When it comes to a girl, start with friendship only, and then eventually you may be able to graduate to hand holding. But for your sake I wouldn't suggest you go much further than that before marriage. Be focusing instead on God. Be focusing instead on preparing yourself (physically, emotionally, and spiritually) for the man He wants you to be. And when you're ready, He will bring to you the right girl.
These temptations are not a game, and they are not an easy plight to navigate... trust me I know. But hold fast to the Lord and His word, and He will give you strength. It will be difficult, but the end result is divinely worth it. You will stumble and you will sin, we will all fall short of the glory of God, but as long as you give it your best effort, and leave the rest to Christ, you'll be good. Nothing we do (or don't do) will ever be good enough, but thank God,
Christ is. And it is only because of Him we have the opportunity to seek, and one day obtain, perfection. Cling to that hope, and it will guide you through.
Let me know how I may pray for you!
