Christian and dating purity
If she was living in sin at some point, don’t let that hinder you from seeing who Christ has made her right now.
Your identity needs to be rooted in Jesus, not in her and her perfections. Even if you think she has lived a “pure life,” that is not going to fill you and make you feel like the man you hope she will make you feel like.
It’s tempting, therefore, for men, including Christian men, to focus too much on the exterior of a woman and not enough on her internal beauty (or lack of internal beauty).
Likewise, you may not be blown away by a woman’s external beauty the first time you meet her, but if she starts showing interest, thinks you’re funny, really respects you, thinks you are a strong man of God, and wants you to lead and love her, watch out because fireworks are about to fly.
Therefore you will need to be wise and know yourself.
If you enter into your marriage with a sexual addiction it will probably get worse once you get married.
So my second piece of Christian advice for men would be: Stop pursuing porn and start pursuing a real life partner, in that order.
