"We proclaim the gospel to the world so that they may be saved."
The story of Philip and the Ethiopian eunuch in Acts 8 is absolutely astounding. An angel told him where to go (v. 26), the Spirit told him who to talk to (v. 29), and the Ethiopian man asked him to teach the Bible to him (v. 31). Philip proclaimed the gospel of Jesus to him (v. 35) and the man believed and was baptized (v. 38). After that, the Spirit raptured Philip to a city dozens of miles away.
Well, that was easy!
