The conversion of the Ethiopian Eunuch through Isaiah 53 is an evangelistic ministry of Philip. The Holy Spirit is in charge, but evangelism is not apart from human responsibility. The Ethiopian is as ready as one can be to believe. Compare that to Paul, the prime persecutor of the Christian faith. Who would think his hostility could be turned around? Is there someone in your periphery you have written off because of their strong defenses? Relax, persevere, befriend, pray and trust, but be ready to deliver the Truth that you know. This lesson focuses on substitution, a foreign concept in our culture, but the major theme found consistently throughout the Old Testament, occurring prior to Israel and developed throughout Israel’s history and worship. See how the person of Christ and God’s judgment of us through His substitutionary death is undeniably stated in this passage so that we can know that Israel’s Servant can be none other than Jesus Christ.
