Mark 9:29

And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him.

And I set my face unto the Lord God, to seek by prayer and supplications, with fasting, and sackcloth, and ashes:

And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.

Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;

In weariness and painfulness, in watchings often, in hunger and thirst, in fastings often, in cold and nakedness.

For this thing I besought the Lord thrice, that it might depart from me.

Then goeth he, and taketh to him seven other spirits more wicked than himself; and they enter in, and dwell there: and the last state of that man is worse than the first.

But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.

And when they had ordained them elders in every church, and had prayed with fasting, they commended them to the Lord, on whom they believed.

Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation.
