21 In answer Jesus said to them: “Truly I say to you, if you have faith and do not doubt, not only will you do what I did to the fig tree, but even if you say to this mountain, ‘Be lifted up and thrown into the sea,’ it will happen.+

23 Truly I say to you that whoever tells this mountain, ‘Be lifted up and thrown into the sea,’ and does not doubt in his heart but has faith that what he says is going to happen, he will have it happen.+

6 Then the Lord said: “If you had faith the size of a mustard grain, you would say to this black mulberry tree,* ‘Be uprooted and planted in the sea!’ and it would obey you.+
