Philip preached Jesus to the Ethiopian eunuch from Isaiah 53. He could have taken his gospel message from anywhere in the Bible, for all Scripture testifies of Christ (John 5:39). This is Christ-centered or gospel-centered preaching: Showing how the written Word points to the Living Word. When the Ethiopian heard the good news, he believed and was baptized. For this kind of preaching calls for a response. The preacher that doesn’t preach Christ, hasn’t preached. True biblical preaching always points to Christ (1 Cor. 2:2).
