21 Jesus replied, "Truly I tell you, if you have faith and do not doubt, not only can you do what was done to the fig tree, but also you can say to this mountain, 'Go, throw yourself into the sea,' and it will be done.
21 Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this which is done to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done.
English Standard Version
21 And Jesus answered them, "Truly, I say to you, if you have faith and do not 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 thrown into the sea,' it will happen.
21 But Jesus was matter-of-fact: "Yes - and if you embrace this kingdom life and don't doubt God, you'll not only do minor feats like I did to the fig tree, but also triumph over huge obstacles. This mountain, for instance, you'll tell, 'Go jump in the lake,' and it will jump.
New King James Version

New Living Translation
21 Then Jesus told them, "I tell you the truth, if you have faith and don't doubt, you can do things like this and much more. You can even say to this mountain, 'May you be lifted up and thrown into the sea,' and it will happen.
This cursing of the barren fig-tree represents the state of hypocrites in general, and so teaches us that Christ looks for the power of religion in those who profess it, and the savour of it from those that have the show of it. His just expectations from flourishing professors are often disappointed; he comes to many, seeking fruit, and finds leaves only. A false profession commonly withers in this world, and it is the effect of Christ's curse. The fig-tree that had no fruit, soon lost its leaves. This represents the state of the nation and people of the Jews in particular. Our Lord Jesus found among them nothing but leaves. And after they rejected Christ, blindness and hardness grew upon them, till they were undone, and their place and nation rooted up. The Lord was righteous in it. Let us greatly fear the doom denounced on the barren fig-tree.
