Matthew 17:19-21 Then the disciples came to Jesus privately and said, "Why could we not cast it out?" 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. However, this kind does not go out except by prayer and fasting."
Romans 8:26 Likewise the Spirit also helps in our weaknesses. For we do not know what we should pray for as we ought, but the Spirit Himself makes intercession for us with groanings which cannot be uttered.
James 5:16 Confess your trespasses to one another, and pray for one another, that you may be healed. The effective, fervent prayer of a righteous man avails much.
