Mark 9:14-29 describes Jesus healing a demonized boy after His own disciples had failed to deliver him. From this account we can learn six practical lessons:
1. The Christian life alternates between refreshment and warfare (v14).
2. Satan is cruel to all, even children (v17-18,20-22).
3. Jesus can set any captive free (v19,25-27).
4. Jesus abhors unbelief (v19).
5. Jesus honors spiritual honesty (v24).
6. Spiritual power is obtained through believing prayer (v23,28-29).
