Matthew 17:14-21, NKJV
14And when they had come to the multitude, a man came to Him, kneeling down to Him and saying, 15“Lord, have mercy on my son, for he is an epileptic and suffers severely; for he often falls into the fire and often into the water. 16So I brought him to Your disciples, but they could not cure him.” 17Then Jesus answered and said, “O faithless and perverse generation, how long shall I be with you? How long shall I bear with you? Bring him here to Me.” 18And Jesus rebuked the demon, and it came out of him; and the child was cured from that very hour. 19Then the disciples came to Jesus privately and said, “Why could we not cast it out?” 20So 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. 21However, this kind does not go out except by prayer and fasting.”
- Unbelief makes mountains unmovable.
- Faith is powerful in small quantities
- “Impossible” is not in God’s vocabulary
- Prayer requires sacrifice
