The various sects who consider themselves servants of the world of humanity are possessed of good intention, but they are inert, not active; captive, not free; silent, not eloquent; slow, not fast. They have sluggish movement and great intention. These two do not agree.
Many a good intention was there in the world of existence which left no trace, for it was not confirmed by the effective power. But the good intentions of the beloved of God and the merciful projects of the real friends are enforced by the power of the Word of God; therefore, it is effective and quick in action and the means of life to the world of humanity. Thank thou God that He hath provided such a means for thee that by divine aid, heavenly confirmation, merciful intention and heavenly power thou mayest arise to serve, so that thou mayest see wonderful signs and marvelous results.
