The bible is clear when it explains that if we are already a believer then we shouldn’t marry, or yoke ourselves with, an unbeliever. If you do, you’re just asking for trouble. Your spouse might even eventually lead you away from Christ. But what if you became a believer after you got married? What do you do then? Well the bible has something to say about that too. Paul shares this with the church in Corinth in first Corinthians chapter 7 verse 17 which says:
"Nevertheless, each person should live as a believer in whatever situation the Lord has assigned them, just as God has called them. This is the rule I lay down in all the churches."
Earlier in verses 12 and 13 Paul says,
“If any brother has a wife who is not a believer and she is willing to live with him, he must not divorce her. And if a woman has a husband who is not a believer and he is willing to live with her, she must not divorce him.”
So just as you were a mess before you believed in Christ, your situation may be a mess after you’ve accepted him. But Paul tells us that if we find ourselves in that place, that we should live as a believer in the situation the Lord has assigned us. So if you are a new believer now yoked with an unbeliever, I encourage you not to make any drastic changes in where God has you. Live for Him and allow the Holy Spirit to direct your future. It may be incredibly difficult, but keep your eyes on Jesus. He knows your situation and may want to use you right where you are.
“Each person should live as a believer in whatever situation the Lord has assigned them.” When we come to Christ, we are a new creation. It may take time for the Holy Spirit to help us conform to the likeness of Jesus, but your life is headed in that direction if you let the Spirit take control. Likewise, it may take time for your current life situation to align with Christ as well. Yes, if there is sin in your life, you will need to deal with that right away. But if your spouse, or your life situation doesn’t lead you into sin, but at the same time isn’t exactly conducive to an easy walk with Christ, I encourage you not to make any drastic changes, but live for Christ and let the Holy Spirit direct your future.
