What sustains and unites the church is not a pastor or a program, nor is it preferences concerning music. What sustains and unites the church is perseverance in the gospel. In this message from 1 Timothy 1:3–20, David Platt highlights the centrality of the gospel in the life of the church. The apostle Paul highlights the role of the law as well as the mercy that God showed him as the “foremost” sinner. This same mercy in Jesus Christ remains the church’s only hope, which is why we must guard the gospel.
