What makes the gospel so unique? In the sermon “The Content of the Gospel,” Dr. Martyn Lloyd-Jones opens Acts 8:35 and shows how the good news of Jesus Christ is not a message of human invention. The gospel of Christ is by design opposed to the ways of sinful people who do not know God. For this reason, it is a great stumbling block to Jew and Gentile alike. This is because the Christian message is one of salvation from sins by the atoning work of Jesus Christ, who died upon a cross so that all who are sinful could be counted righteous before God. So, it is not a matter of personal experience nor is it about mystical revelations. The truth of Christianity is revealed truth and it is found in God’s holy and inspired word. This is the sure and steady foundation for Christianity, for in it is all that is needed to achieve godliness and holiness. It is in this word that the truth of what Jesus Christ did on Calvary’s cross is found. When the Christian stands to proclaim the truth of God and His Son, Jesus Christ, they do not come on the basis of experience, but with the very words of the living God.
