Historical Context
First-century Judaism practiced fasting for spiritual purposes, particularly in connection with prayer for divine intervention. Jesus fasted forty days before beginning ministry (Matthew 4:2). The early church continued this practice (Acts 13:2-3, 14:23). This teaching came shortly before Jesus' Passion, preparing disciples for coming trials requiring intense prayer.

Analysis & Commentary
Jesus explains the disciples' failure to cast out the demon: 'this kind goeth not out but by prayer and fasting.' Some spiritual battles require extraordinary dependence on God. While many manuscripts omit 'and fasting,' the principle remains: certain ministries demand concentrated devotion and self-denial. Reformed practice recognizes prayer and fasting as means of grace, not earning God's favor but expressing desperate dependence. The disciples' failure despite previous successes (Matthew 10:8) shows that past victories don't guarantee present power—continuous reliance on God is essential.
