Matthew 17:20  (King James Version)
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.

17 ; Matthew 14:30 Matthew 14:31 Hebrews 3:19

21:21 Mark 11:23 ; Luke 17:6 ; 1 Corinthians 12:9 ; 13:2

That is, as Bp. Pearce well remarks, a thriving and increasing faith, like a grain of mustard seed, which, from being the least of seeds, becomes the greatest of all herbs.
