'Little Faith' in the Bible

Now if God so gorgeously dresses the wild grass which today is green but tomorrow is tossed into the furnace, will He not much more surely clothe you, O you with little faith?

And He said to them, "Why are you afraid, O you with little faith?" Then He got up and rebuked the winds and the sea, and there was a great calm.

Jesus at once put out His hand and caught hold of him, and said to him, "O you of little faith! Why did you waver so?"

Jesus knew it and said, "Why are you discussing among yourselves the fact that you have no bread? Have you so little faith?

He answered them, "Because you have so little faith! For I solemnly say to you, if you have the faith that is living like a grain of mustard, you can say to this mountain, 'Move over from here to yonder,' and it will move over, and nothing will be impossible for you to do."

Now if God so gorgeously dresses the wild grass which today is green but tomorrow is tossed into the furnace, how much more surely will He clothe you, O you with little faith?
