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.
Ver. 21. If ye have faith and doubt not] Or dispute not the matter as probable only and somewhat uncertain, but not altogether undoubted. a He that doubteth debateth it, as it were, with himself, puts the case to and fro, sometimes being of one mind, sometimes of another. Now "let not such a man think that he shall receive anything of the Lord," James 1:7; "If ye will not believe, surely ye shall not be established," Isaiah 7:9 .
