Matthew 17:21 speaks of a specific kind of spiritual breakthrough that requires both prayer and fasting. Jesus makes it clear that some spiritual challenges cannot be overcome unless we actively engage in both practices. Fasting, in combination with prayer, helps to increase our faith and spiritual power. It serves as a reminder that certain situations or strongholds in life require a deeper level of spiritual commitment, one that involves denying ourselves and seeking God with greater intensity. Fasting humbles our hearts and strengthens our reliance on God, allowing us to tap into His power and wisdom. This verse teaches us that when we face situations that seem beyond our ability, prayer and fasting are essential tools for overcoming obstacles and engaging with God’s divine authority. In fasting, we are empowered to face life’s challenges with greater faith and reliance on God’s strength.
