It is not our great faith but faith in a Powerful God.
Look to the greatness of our God.Matt 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.
Matt 13:31-32 (King James Version) Another parable put he forth unto them, saying, The kingdom of heaven is like to a grain of mustard seed, which a man took, and sowed in his field: Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof.
In our trials of faith we often try to muster up more faith instead of focusing upon the expectation.
