Matthew 17:20 (ESV) 20 He said to them, “Because of your little faith. For truly, I say to you, if you have faith like a grain of mustard seed, you will say to this mountain, ‘Move from here to there,’ and it will move, and nothing will be impossible for you.”
John 4:31-38 (ESV) 31 Meanwhile the disciples were urging him, saying, “Rabbi, eat.” 32 But he said to them, “I have food to eat that you do not know about.” 33 So the disciples said to one another, “Has anyone brought him something to eat?” 34 Jesus said to them, “My food is to do the will of him who sent me and to accomplish his work. 35 Do you not say, ‘There are yet four months, then comes the harvest’?

Mark 4:26-27 (NASB) 26 And He was saying, “The kingdom of God is like a man who casts seed upon the soil; 27 and he goes to bed at night and gets up by day, and the seed sprouts and grows—how, he himself does not know.
