In this sermon on Colossians 1:3–7 titled “A Body of Truth,” Dr. Martyn Lloyd-Jones focuses on a fundamental question: What is Christianity? Paul writes to the early church in Colossae, congratulating them on their love for God’s people. He also affirms the gospel they heard from Epaphras, a fellow servant of God and a friend of Paul’s. The church in Colossae, Dr. Lloyd-Jones explains, was not so different from the other early churches in the New Testament. It was most likely a collection of new believers, united by the gospel, meeting in a home to discuss and study the Old Testament. This, Dr. Lloyd-Jones says, is what Christianity is about. It is not about catching a feeling, as if Christianity were a disease. He says the core of Christianity is the gospel. Dr. Lloyd-Jones says it is about understanding and explains that Christ came for the redemption of sin, and whoever believes in Him has eternal life. Although Christians may argue among themselves, this incredible doctrine should remain central. In closing, he invites those who have yet to receive this salvation to accept God’s grace.
