The mere fact that He can move on your behalf brings Him Glory. To be able to heal, to be able to strengthen, to be able to show you his unchangeable nature. Gives Him great glory and great honor. For faith is a exact representation of the Kingdom Of God.
Luke 13:18,19
18 Then said he, Unto what is the kingdom of God like? and whereunto shall I resemble it? 19 It is like a grain of mustard seed, which a man took, and cast into his garden; and it grew, and waxed a great tree; and the fowls of the air lodged in the branches of it.
Faith like a seed produces abundantly.
