If sex before marriage is a sin, why do Christians do it? I know many Christians who have, and very few who haven't. In this day and age, it seems outdated to wait. How do you find a guy who is willing to wait?
Christians are supposed to be outdated. The fashions and trends of the world are often against the teaches of God.
So why do Christians have sex before marriage? The peer pressure to be like others, to be cool, to do what everyone else is doing is strong. The sex drive is strong, particularly in young people who are in love.
You really can wait, though, and on your wedding night, you and your husband will be glad you waited. Any boyfriend who breaks up with you because you wouldn't have sex with him is probably not the Christian partner you want to share your life with.
I know many believers who didnt have sex with their partner till they married. It depends on whether you think we should obey God or disobey Him. Waiting for marriage gives that marriage a far better start than if you don't. A marriage that begins in sin will affect that marriage even if the couple do repent.
I think that many believers put their own desires before what is right, and many have low moral values and not much integrity. A true believer will know that its wrong, so its a question of God leading you to the right guy. If a man sleeps around I would have to question how strong his faith is, and personally I wouldn't go near him.
