Unfortunately, the problem of sexual immorality did not bypass the body of Christ. While I have heard these things before, they didn't really sink in until recently. First, let's not deny that it is a very significant problem. Recognizing the problem is a key step in dealing with it. Second, let's avoid changing the gospel message as a solution.
Lordship salvation has a deep concern that believers live holy lives.
I share that concern. However, the solution which Lordship salvation offers, adding works to the gospel, is one I cannot adopt. Salvation is a free gift. It is received by faith alone, not by faith plus works. To tell a person that he or she must stop living with their lover in order to be saved from hell is to contradict the idea of a free gift.
