If you truly love each other, you will wait until marriage! Because you want to preserve one another in purity for the day when you can say without reservation to each other; I am yours and your mine. Without reservation, because you have pledged to each other, before God’s church and in sight of men that you accept full responsibility for one another. That moment is called marriage. To insist on union before that moment is to ask for the full privilege without accepting the total responsibility. This is sinful, selfish and unloving.
True love will wait because in God’s design, sexual union is the culmination (not the initiation) of true love, the supreme act of mutual self giving. It is the out ward, physical expression of a deeper spiritual union between two persons “and the two shall become one”.
