19 Then came the disciples to Jesus apart, and said, Why could not we cast him out?
20 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.
-As you might know or imagine, mustard seeds are very small and the analogy of a mustard seed was often used by the Jews to signify something of little weight or size. Jesus tells us that even a tiny amount of faith can move mountains. But notice the accusation wrapped up in these verses of scripture; “If ye have faith as a grain of mustard seed…” By saying “if”, isn’t Jesus telling the disciples that they lack faith even the size of a mustard seed? There are two very good reasons why a little faith is able to go a long way: 1) Little is always much when God is in it and 2) Little has to be enough because if we are honest with ourselves, there are not too many of us walking around with faith the size of watermelons.
