Last night during our Bible study we came across this verse from Psalm 119:9
How can a young person stay pure?
By obeying your word.
That's it. Those are the rules. Do you want to know how to keep your relationship from going 'too far' then get into God's Word and see what He says. Not only that, but you have to do what He says!
I loved the Joshua Harris books: I kissed Dating Goodbye, and Boy Meets Girl and highly recommend them to those wanting to go a different route than most. However, when it came time for my own love story things didn't go quite according to how I pictured they would. For starters, I was in Thailand, and my then boyfriend was in the States. We didn't physically date until 9 months after we met through a mutual friend on Facebook. This meant that all those 'rules' that the books and conferences suggested had no meaning for my particular situation. What did we do?
I think it helped that both he and I had a desire for purity. If your boyfriend or fiance doesn't have the same desire for purity that you have, then you don't need to be in the relationship. More than likely, he will cause you to do things that you don't want to do, and to go farther than you want to go. So, having a significant other that has a relationship with God (and not just one that says he's a Christian but doesn't live like one) is vital for a pure relationship.
Second, we told each other that we would put God first in the relationship instead of each other. We then got on the same page as far as once we did meet, what we would do physically. Now, here comes the tricky part, because you have to decide what you will do to keep your relationship pure. For us, we stayed where people were, held hands, but never kissed. Actually, my husband never told me he loved me until he asked me to marry him, and we never kissed until our wedding day. This is what we did, and once we set up those guidelines for ourselves it lifted the burden of knowing whether or not we were going too far. It allowed trust to be built between each other. Since we often skyped while we were alone, knowing each others heart and intentions made it where we never ventured into the 'unknown' (you know, the after marriage stuff) or 'too far' category.
I said all that to say, you have to read the Bible, you have to set the guidelines with yourself and with your significant other. You both need to be in the Word. Because it doesn't matter how many conferences you go to, or books you read, your heart needs to be in the right place.
