Hebrews 11:1

But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.

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.

⁵Trust in the Lord with all thine heart; and lean not unto thine own understanding. ⁶In all thy ways acknowledge him, and he shall direct thy paths.

And we know that all things work together for good to them that love God, to them who are the called according to his purpose.

For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
