The happiest marriages are preceded by a proper courtship period. Waiting is what makes getting married so awesome and fulfilling. When couples have physical intimacy outside of marriage, the sacredness of the marriage bed is gone, cheapened, innocence is forever gone, and the special meaning of intimacy will never be the same. Satan knows this and wants to kill, steal and destroy your happiness. I cannot think of anything more sad, than a woman marrying the man of her dreams, having only a defiled body to offer him, handled by unholy hands by some bum who used her as a dog peeing on a fire-hydrant. That cannot happen to you if you get legally married first.
Since situations lead to temptation, a couple ought never be alone together until they get married. We need a revival of the importance of little things in America. The ungodly world scoffs at the idea of abstinence from drinking booze at all, but the fact is you cannot take two drinks of you don't take the first. The heathen world scoffs at the idea that women ought not wear pants. But there wouldn't be so many broken marriages and abortions if women clothed themselves properly. The way a woman dresses has a profound impact upon her behavior (1st Timothy 2:9). When I see a woman in a long modest dress, my first impression is that she is a Christian who loves God and righteousness. A woman in pants tells me that morality doesn't mean much to her, and that she doesn't care or understand how the man's mind works. You have no idea ladies of what goes through a man's mind when he sees a woman's buttocks and thighs. If you did, you'd either be scared or it would thrill your perverse soul.
