Luke 17:6

And the Lord said, If ye had faith as a grain of mustard seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea; and it should obey you.

Ver. 6. If ye had faith as a grain of mustard seed] Faith as a grain of mustard seed is parva, humilis, sed et acris, fervida, small and low, but also sharp and lively; it must have acrimony and vivacity, and then it may remove mountains.

Ye might say unto this sycamine tree, &c.] That was a senseless slander of the Jews, that Christ stole the true name of God out of the holy of holies, by which means he wrought all his miracles; and that, lest he should lose it, he cut a hole in his thigh, and sewed it therein. Get we but the true faith of God closed up in our hearts (that most holy faith, as St Jude Jdg 1:20 calleth it), and you may work wonders. See Trapp on " Mat 17:20 "
