35 Then Philip opened his mouth, and beginning at this Scripture, preached Jesus to him. 36 Now as they went down the road, they came to some water. And the eunuch said, “See, here is water. What hinders me from being baptized?” (Acts 8:35–36, NKJV)
This passage is particularly instructive about what it means to preach Jesus. Preaching Jesus identifies Him as the suffering Servant of God who sacrificed His life (Acts 8:32-34; Isa. 53:7-8). It includes teaching about sin and salvation from it. The Ethiopian was lost, and wanted to be saved. The water would facilitate his salvation. When he asked Philip about baptism, he had not yet announced his personal faith in Jesus, since Philip stated that as the condition upon which he could be baptized (v. 37). To preach Jesus means preaching baptism, since the Ethiopian immediately asked about it when he saw water. How else did he know about baptism, expect that Philip spoke of it when he “preached Jesus” to him? Surely, he told the man what Jesus preached about baptism: “He that believes and is baptized will be saved” (Mk. 16:16). The Ethiopian confessed his personal faith, stopped the chariot, and Philip baptized him (Acts 8:37-38). The man joyfully went on his way, because he was saved when he believed and was baptized. Christ continues to save sinners the same way, today. What hinders you from being baptized to be saved?
