Luke 17:6
He replied, if you have faith as small as a mustard seed, you can say to this mulberry tree, be uprooted and planted in the sea, and it will obey you — the mustard-seed faith: the smallest conceivable faith is sufficient for the impossible command. The mulberry tree uprooted and planted in the sea is the kingdom's paradox-idiom for the genuinely impossible. The point is not that more faith is needed but that any genuine faith is sufficient.
