Some things are not acceptable in a Christian marriage. When physical abuse, sexual unfaithfulness, sexual abuse of children, alcoholism, or drug addiction persist in a marriage, it is time to take loving action. In fact, one is not loving when he or she accepts such behavior as a way of life. This behavior is destroying the individual and the marriage.
Love must confront. In the Bible, confronting is always seen as redemptive. Jesus said that if someone sins against us, then we are to confront them. If they listen and repent, we are to forgive, and the relationship is healed. If they do not repent we are to take additional steps of tough love. The purpose is not revenge, but redemption. That’s tough love and that’s real love.
