Can Christians marry unbelievers? According to the Bible, no. It says: "Do not submit to someone who does not believe in God - Christ and Satan cannot be united". Bill Graham expressed this very accurately several years ago, when he said that the person who marries n atheist obtains the devil himself as a father-in-law. When Christian singles marry atheists, their inner world is shaken.
Some Christians nevertheless follow this way and marry unbelievers, hoping to turn them to God after the wedding. But if the Lord actually designed this woman or this man for you, this person would have been attracted by religion before you met. If it did not happen, this means God does not welcome this marriage. Christian singles must learn to wait until their decisions are confirmed by God. Any other resolution could turn out to be a great mistake.
