Matt 17:20 He answered, “Because of your little faith [your lack of trust and confidence in the power of God]; for I assure you and most solemnly say to you, if you have [living] faith the size of a mustard seed, you will say to this mountain, ‘Move from here to there,’ and [if it is God’s will] it will move; and nothing will be impossible for you. Often when we think of faith we often say that we want faith the size of a mustard seed not realizing that a mustard seed grows into a big tree. It is not the kind of seed that remains tiny and restricted in that little seed coat. It grows exponentially and bears many many more seeds. That is the faith we should have not the kind that stays small and unproductive. It has to grow! It has to keep growing! That is the whole point. Don't want faith that stays small, want faith that grows.
