The Advantages of Fasting and Prayer

Matthew 17:18-21 New King James Version

 

¹⁸ And Jesus rebuked the demon, and it came out of him; and the child was cured from that very hour.

¹⁹ Then the disciples came to Jesus privately and said, “Why could we not cast it out?”

²⁰ So Jesus said to them, “Because of your unbelief; for assuredly, I say to you, if you have faith as a mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move; and nothing will be impossible for you. ²¹ However, this kind does not go out except by prayer and fasting.”
