Jesus answered and said ... - Jesus took occasion from this to establish their faith in God, Mark 11:22

He told them that any difficulty could be overcome by faith. To remove a mountain denotes the power of surmounting or removing any difficulty. The phrase was so used by the Jews. There is no doubt that this was "literally" true - that if "they had the faith of miracles," they could remove the mountain before them - the Mount of Olives - for this was as easy for God to do by them as to heal the sick or raise the dead. But the Saviour rather referred, probably, to the difficulties and trials which they would be called to endure in preaching the gospel.

If ye have faith, and doubt not - See on Matthew 17:20 (note). Removing mountains, and rooting up of mountains, are phrases very generally used to signify the removing or conquering great difficulties - getting through perplexities. So, many of the rabbins are termed rooters up of mountains, because they were dexterous in removing difficulties, solving cases of conscience, etc. In this sense our Lord's words are to be understood. He that has faith will get through every difficulty and perplexity; mountains shall become molehills or plains before him. The saying is neither to be taken in its literal sense, nor is it hyperbolical: it is a proverbial form of speech, which no Jew could misunderstand, and with which no Christian ought to be puzzled.

Jesus answered and said unto them,.... His disciples wondering at his power, in causing the fig tree to wither so suddenly:

verily I say unto you, if ye have faith; that is, in God, in his power, which reaches to all things: the object of faith is expressed in Mark, and by way of exhortation, "have faith in God", that he will enable you to perform whatsoever ye shall desire; which must be understood, not of spiritual faith in the promises of God, and person of Christ, but of, the faith of miracles, or faith in the power of God to perform things that are above the strength of nature:

and doubt not; either of the power, or will of God to do for you, and by you, the thing desired; for this kind of faith would not admit of the least degree of doubting: there must be no hesitation in the mind, no reasoning upon the thing, how it can be performed; the mind must not be divided between the power and will of God, and the difficulties and discouragements which attend the case, but must believe in hope against hope, with a full persuasion of accomplishment: for want of this faith, without doubting, the disciples could not cure the child that was lunatic.

Ye shall not only do this which is done to the fig tree; cause one to be dried up, and wither away by a word, as Christ had done to this, which, comparatively speaking, was but a lesser sort of miracle;

but also, if ye shall say to this mountain; the Mount of Olives, where Christ and his disciples now were, and were passing over, or, at least, were very near it; or any other mountain wherever they might be, to which they should, upon any occasion, think fit to say,

be thou removed, and cast into the sea; which was many miles off from Mount Olivet, and must he a very surprising performance for a mountain to be rooted up, so large as that was, and be carried several miles from its former situation, and be thrown into the sea; and yet, as difficult and amazing as this may seem,

it shall be done: that is, provided the person doubts not; or, as it is said in Mark, "shall not doubt in his heart, but shall believe that those things, which he saith, shall come to pass, he shall have whatsoever he saith": for this must not be confined to the particular instances of drying up a fig tree, or removing a mountain, but the doing of any sort of miracle, how great soever. Nor is it our Lord's meaning that they should do these particular things; nor is it certain that they ever did: but his sense is, that, had they faith, they should be able not only to do such lesser miracles, as, comparatively speaking, the withering of the fig tree was, but they should be able to perform things much more difficult and surprising, whenever the good of the souls of men, the propagation of the Gospel, and the glory of God required them.

{5} Jesus answered and said unto them, Verily I say unto you, If ye have faith, and {i} 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.

(5) How great the force of faith is.

(i) The Greek word signifies a fixing or wavering of mind, so that we cannot tell which way to take.

21:21,22 If ye have faith. See PNT Mt 17:19.

21:21 Jesus answering, said, If ye have faith - Whence we may learn, that one great end of our Lord in this miracle was to confirm and increase their faith: another was, to warn them against unfruitfulness. Mt 17:20.

21:18-22 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.
