Forfeit God's Blessing

A Christian should not marry an unbeliever because he or she forfeits God's blessing.

"I have heard that you are intending to marry a man who is not a believer. I am unable to write you a long letter, but I will say if you take this step you depart from the plainest injunction of God's Word and cannot expect or claim His blessing upon such a union. All the promises of God are on condition of obedience to Him." --Ellen G. White, Letters to Young Lovers, p. 83
