While Peter, James and John were experiencing the glory of Christ on the mountain (as we saw in last week’s passage), the other nine disciples were involved in an embarrassing situation in the valley below. A distraught father had brought his demon-possessed son to the disciples to heal, but they were unable to deliver the boy. This created a perfect opportunity for the religious to begin arguing with the disciples over this failure, trying to discredit them before the people. But when Jesus is brought into the situation, He not only delivers the boy from the demon, but He also uses this as an opportunity to prepare His disciples for the necessity of walking by faith. For us, we learn that although our attempts to serve may fail, the will of Jesus will always prevail. We also learn that failure is never our foe, because it gives us an opportunity to renew our trust in Jesus.
