Matthew Chapter 17, Verse 20
From BibleWiki
20: ο δε ιησους ειπεν αυτοις δια την απιστιαν υμων αμην γαρ λεγω υμιν εαν εχητε πιστιν ως κοκκον σιναπεως ερειτε τω ορει τουτω μεταβηθι εντευθεν εκει και μεταβησεται και ουδεν αδυνατησει υμιν
20: And Jesus said unto them, Because of your unbelief: for verily
I say unto you, If ye have faith as a grain of mustard seed,
ye shall say unto this mountain, Remove hence to yonder place;
and it shall remove; and nothing shall be impossible unto you.
20: But this kind is not cast out but by prayer and fasting.
As a grain of mustard seed. See Barnes "Mt 13:31, Mt 13:32".
The mustard seed was the smallest of all Seeds. It has been supposed by some, therefore, that he meant to say, if ye have the smallest or feeblest faith that is genuine, ye can do all things. The mustard seed produced the largest of all herbs. It has been supposed by others, therefore, to mean, If you have increasing, expanding, enlarged faith, growing and strengthening from small beginnings, you can perform the most difficult undertaking. There is a principle of vitality in the grain of seed, stretching forward to great results, which illustrates the nature of faith. Your faith should be like that. This is probably the true meaning.
Ye shall say unto this mountain, etc. Probably he pointed to a mountain near, to assure them, if they had such faith, they might accomplish the most difficult undertakings - things that at first would appear impossible.
