power of prayer

Prayer is, and God has decreed that it should be, a power in the universe, as distinct, as real, as natural, and as uniform, as the power of gravitation, or of light, or of electricity. A man may use it, as trustingly and as soberly as he would use either of these. It is as truly the dictate of good sense, that a man should expect to achieve something by praying, as it is that he should expect to achieve something by a telescope, or the mariner’s compass, or the electric telegraph.
