Samaria was specifically mentioned by the Lord for his disciples to bear testimony of him there (Acts 1:8). The people here have a heathen background. "Philip the evangelist" (Acts 8:5; 21:8), "full of the Holy Ghost and wisdom went down to the city of Samaria, and preached Christ unto them" (Acts 8:5). His preaching held them "spellbound." He continued to preach Christ to a People deceived by sorcery and witchcraft (Acts 8:9-11), and his preaching accomplished confidence. "But when the believed Philip preaching " (Acts 8:12). Their baptism into Christ evidences their "turn" or repentance. ( Luke 24:47.) Luke says they were baptized, both men and women (Acts 8:12).
"He that believes and is baptized shall be saved." -Jesus
