In this text we look at three episodes that have one thing in common: something critical is missing. Apollos’ teaching is accurate but incomplete. The twelve men Paul meets in Ephesus likely had never heard the full gospel and believed in Jesus. Finally, seven Jewish exorcist brothers simply “tack on” the name of Jesus in a ministry venture and get throttled for their inadequacy. All together, this narrative is a powerful witness to the importance of becoming and remaining teachable.
