Luke 13:18-19 He said therefore, “What is the kingdom of God like? And to what shall I compare it? It is like a grain of mustard seed that a man took and sowed in his garden, and it grew and became a tree, and the birds of the air made nests in its branches.”

Matthew 13:31-32

He put another parable before them, saying, “The kingdom of heaven is like a grain of mustard seed that a man took and sowed in his field.

It is the smallest of all seeds, but when it has grown it is larger than all the garden plants and becomes a tree, so that the birds of the air come and make nests in its branches.”

Matthew 17:20

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.”

Mark 11:22-24

And Jesus answered them, “Have faith in God.

Truly, I say to you, whoever says to this mountain, ‘Be taken up and thrown into the sea,’ and does not doubt in his heart, but believes that what he says will come to pass, it will be done for him.

Therefore I tell you, whatever you ask in prayer, believe that you have received it, and it will be yours.
