Richard Blackaby says: I have known many a Christian who was deeply concerned because a husband or wife is an unbeliever. As the result, the believer would continually speak to his or her partner about the need for God. However, this persistence at times actually frustrated the non-believer and drove the spouse further from God. When the Christians come to me and tearfully share that they have done all they know to do but their mate seems more reluctant than ever, I suggest they may be attempting to do what only the Holy Spirit can do. “Instead of trying to convict your spouse of sin,” I say, “pray for your spouse daily and then watch to see when the Holy Spirit prepares him or her for a spiritual conversation.”
