Acts 8:30

Philip ran. That is, ran up to the chariot, in immediate obedience to the Spirit’s command. Christians should emulate this ready response. Those who do so will find more people ready to listen to sincere, Christ-centered conversation than they would ordinarily expect.

Understandest thou? Note the skillful opening of the conversation: Philip began just where he found the man, and suited his approach to his prospect’s interests. In this he provides an example for every Christian worker to follow. Philip’s question referred to the meaning rather than the words. Its form in Greek implies that he expected a negative answer. The eunuch might have heard some of the Jewish expositions of the passage, but he probably had no inkling of the fact that the words referred to Jesus Christ. But Philip knew their meaning, and was led by the Spirit to explain their import.
