From the Holy Bible:
“And when they were come to the multitude, there came to him a certain man, kneeling down to him, and saying,
Lord, have mercy on my son: for he is lunatic, and sore vexed: for ofttimes he falleth into the fire, and oft into the water.
And I brought him to thy disciples, and they could not cure him.
Then Jesus answered and said, O faithless and perverse generation, how long shall I be with you? how long shall I suffer you? bring him hither to me.
And Jesus rebuked the devil; and he departed out of him: and the child was cured from that very hour.
Then came the disciples to Jesus apart, and said, Why could we not cast him out?
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.” (Matthew 17:14-20)
“With God all things are possible.” (Matthew 19:26)
“Jesus said unto him, If thou canst believe, all things are possible to him that believeth.” (Mark 9:23)
“And Jesus answering saith unto them, Have faith in God.
For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.” (Matthew 11:22-23)
From The Empire Strikes Back:
“We’ll never get it out now…”
“So certain are you? Always with you what cannot be done. Hear you nothing that I say?”
“Master, moving stones around is one thing, this is…totally different.”
“No! No different. Only different in your mind. You must unlearn what you have learned.”
“All right… I’ll give it a try.”
“No! Try not. Do… or do not. There is no try.”
“I can’t. It’s too big.”
“Size matters not. Look at me. Judge me by my size, do you, hm? And well you should not. For my ally is the force, and a powerful ally it is. Life creates it, makes it grow. Its energy surrounds us and binds us. Luminous beings are we, not this crude matter. You must feel the force around you, here, between you, me, the tree, the rock, everywhere… yes, even between the land and the ship.”
“You want the impossible.”
“I don’t believe it.”
“That… is why you fail.”
