Do Christians truly rejoice in Jesus Christ? Do they rejoice in the salvation He has freely given? Listen to this sermon on John 4:13–14 titled “The Need of Man” as Dr. Martyn Lloyd-Jones speaks on salvation and what it reveals. He begins by bringing up the saddening lack of rejoicing most Christians have towards salvation. He explains that this lack comes directly from a failure to see the utter and complete need of Jesus’ salvation. One cannot truly rejoice in the salvation Christ offers if they do not first see their need and realize their complete inadequacy in saving themselves. The whole Bible, especially the Old Testament, points directly to the fact that all need a Savior. People can only be moved by salvation if they see their need for it. Not only do they have to recognize their need, but they have to know their complete need. This is realizing that without Christ and His salvation they are spiritually dead and ignorant. But the good news is that as Christians, they have a Savior who came to earth, died, and rose again victorious over death. He is the deliverer. Let all run to Him, realizing the complete need, and rejoice in His salvation.
