And Jesus perceiving it said, O ye of little faith, why reason ye among yourselves, because ye have no bread?

And he saith unto them, Because of your little faith: 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.

But if God doth so clothe the grass in the field, which to-day is, and to-morrow is cast into the oven; how much more'shall he clothe you, O ye of little faith?
