And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.

What profit hath a man of all his labour which he taketh under the sun?

These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.

John 16:33

Afterward Jesus findeth him in the temple, and said unto him, Behold, thou art made whole: sin no more, lest a worse thing come unto thee.
