Prayer 209 knowledge by God Almighty in advance and our certainty increases as if we have seen God. There is a relationship between prayer and acceptance which has existed ever since man was created. When God Almighty addresses Himself towards the doing of a thing it is His way that some sincere servant of His occupies himself with prayer in restlessness, pain and distress, and devotes the whole of his resolve and attention towards the accomplishment of that objective. Then the prayers of the mortal man draw Divine grace from heaven and God. Almighty creates such new means through which the purpose is achieved. . Though such prayer is apparently offered by man, yet in truth that person is wholly lost in God and at the time of supplication he arrives in the presence of the One and. Glorious with such a stamp of being lost in God that at that time his hand becomes the hand of God Almighty. . Such is the prayer through which God is recognized and the existence of that Glorious One becomes known Who is hidden in thousands of veils. [Ayyām-uş-Şulḥ, Rūḥānī Khazā'in, vol. 14, pp. 238-239]. A foolish one thinks that prayer is a vain and useless thing, but he does not know that it is prayer in consequence of which God, the Glorious, manifests Himself to. His seekers and conveys to their hearts the revelation: "I am the All-Powerful One. " Everyone who is hungry and thirsty for certainty should remember that for the seeker of spiritual light in this world, prayer is the only means which bestows certainty with regard to the existence of. God Almighty and removes all doubts and suspicions. [Ayyam-uş-Şulḥ, Rūḥānī Khazā'in, vol. 14, pp. 239-240]
