"a man who will bring out who she is not just take her"

I was talking with a friend the other day, who had invited a girl to a group event. She is one of those girls that most of the guys find attractive. I told my friend to look after her as a brother. I told him she needed a man who will bring out who she is not just take her. Talking about that with my friend made me think. Do we look for relationships for what we can get out of it or do we look for relationships so that we can serve and build others up. I want to say this to the guys, if you are going to be a husband you have to learn to lay your life down for others (and not just women), or you won’t be able to do this for your wife. It starts now on how you pursue friendships. My relationship with my sisters is not so that I can have a wife, but is to, as a brother, build them up and encourage them in what the Lord has for them. If someday (with much accountability and prayer) building a sister up means marrying them, then so be it, but in the meantime my relationship with my sister’s is not to get my needs met, but to serve.
