My advice is that you should tell her that if you get married, she has to understand that you are going to be serious about Jesus - you will be at church regularly, you will give away money to church and to those in need, and that you will want to raise your children as Christians.(It also means you’ll be a really good husband too!!Thank you for asking a question which affects you so much. I have prayed for you that you will do what is right, though it is not easy.Four months ago, my wife Medina and I celebrated our one year anniversary since we married each other.And you also need to confess to your girlfriend that you’ve been doing the wrong thing by her as well.By living with her, you will have sent a message to her that Jesus is not really all that important to you.I'm not out to prove that it's Biblically ordained, but I do think the Scripture leaves space for debate, and the assertion that "it won't work" just isn't accurate anymore.
The Bible teaches that Christian are free to marry whoever they wish, but they ought to be believers (1 Corinthians ).
No sooner than having ordered Medina's present did I stumble across Kathy Keller's "Don't Take it from Me: Reasons Why You Shouldn't Marry an Unbeliever." While the article is already well over a year old, it recently gained some traction on social media, attracting my attention.
I wanted to take this opportunity to push back both on the assertion, and the way it's framed.
The Christian life then becomes not a question of being good enough for God but being the person God wants you to be - confidently living your life in obedience to Jesus.
So your question should be “what is the obedient thing for me to do in this situation?
