Virginity refers to an event. Its loss might be a past event or a future event, but it is still a one-time occurrence. Purity, on the other hand, is a state of living and a state of being. No matter what our past is, because of Jesus, purity is possible in the present and in the future.
Purity is what Paul means when he tells us to press on. Purity is what Jesus means when He tells the woman caught in adultery to go and sin no more. Virginity will fail us, but purity is always available.
Our virginity status isn’t a pre-requisite for marriage. God cares more that we are currently living in purity than whether we enter marriage a virgin. (Of course, if you’re a virgin, that means God wants you to remain so until marriage.) But if sexual immortality has been confessed, repented of, and forgiven, those specific sins don’t matter anymore. We — and our children — are clean now.
So let’s not talk about virginity, other than to define what it is. Instead, let’s teach our children to walk in the way of purity and commit to walking in that way ourselves.
