"The greatest question that can be asked of the "twice born" ones is, "Have ye received the Holy Ghost since ye believed?" This was the password into the early Church." --L. B. Cowman, Streams in the Desert
Acts 19:1, 2 tells us: While Apollos was at Corinth, Paul passed through the interior and came to Ephesus. There he found some disciples and asked them, "Did you receive the Holy Spirit when you became believers?" "No," they answered, "we have not even heard that there is a Holy Spirit."
