Jesus said, “…If ye have faith as a grain of mustard seed…nothing shall be impossible unto you” (Matthew 17:20).
A big mountain does not require big faith to move it. You only need a small measure of faith, as small as a grain of mustard seed.
Think of the explosives that are normally used to blow up mountains and rocks. They are very small in size compared to the mountain but when it is set in place and left for a few hours, the mountain is blown apart and leveled down. Similarly, every challenge before you is at the mercy of your mustard seed faith
