He said to them, "Because of your little faith. For truly, I say to you, if you have faith as 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 to you."
And Jesus answered them, "Truly, I say to you, if you have faith and never doubt, you will not only do what has been done to the fig tree, but even if you say to this mountain, `Be taken up and cast into the sea,' it will be done.
Truly, I say to you, whoever says to this mountain, `Be taken up and cast 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.
And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but have not love, I am nothing.
It is like a grain of mustard seed which 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."
it is the smallest of all seeds, but when it has grown it is the greatest of shrubs and becomes a tree, so that the birds of the air come and make nests in its branches."
