Now this idea has been used for years to comfort despondent Christians who worry that they’ll never find Mr. or Mrs. Right, and given that we believe God to be all-knowing and all-powerful, there’s a certain sense in thinking that He’s got somebody picked out for us all...Now that just might not be true.
So when you think about that idea for a while, some questions and problems present themselves...For one, if God has somebody “picked out” for you, should you actively search for that person, or trust that God will bring them into your life? How do you know if somebody is “the one”? And what about the gift of singleness?
Paul the writer of 1 Corinthians, stops short of guaranteeing that God will provide a spouse to anyone who wants one... Neither here nor anywhere else does Paul—or any biblical writer—lock God into a required response to any human need... There is always the possibility that God will choose not to meet a need directly but to give the grace to live contentedly with unfulfilled desires, a point Paul stresses in his second letter to this church (2 Cor 12:7-10).
Still Paul puts the accent on hope in his teaching on marriage, and throughout his writings urges us toward faith in a God who provides all of our needs in Jesus Christ (Phil 4:19). If any one want to be married, they certainly have reason to stay hopeful that God will provide someone to meet that need unless he changes their desire or in some clear way shuts the door.
I believe it's important to maintain this hope to keep our expectations within reasonable bounds... If someone is thinking, “God has one ideal choice for them,,” They may be setting their standards for that person impossibly high.... When we consider God’s role which I believe was in Paul’s mind as he wrote 1 Corinthians 7, it seems to be not “God has one ideal person for you to marry”—but “God will help you find a suitable partner.” This is usually a more edifying thought to dwell on...I also believe the person God gives us to marry will have imperfections and failings, just like we do. Still that person will complement you/me in a way that will work for our greater happiness and a more fruitful life together for Christ.
