The essential Will of God can be discussed from two perspectives (ontological and conceptual perspectives), which is the subject of this article. The majority of thinkers are against the appearance of expressions. Theologians have generally denied the essential Will and philosophers have given it to the attribute of knowledge, which is also a denial. In response to the truth of the essential Will of God, the author, after many reflections, has reached a new reading of the essential Will of God (interpreting it to God’s Essence in terms of the fulfillment of the generative meaning of lead, demand, desire to act - equivalent to generosity and grace). In this paper, its foundations and proofs (the will as the description of perfection and existence, the lack of the essential will (the existential perfection), conflict with the purity of God’s Essence, the necessity of the end of all accidents to the substantive, the negation of the essential Will, require the denial of God’s Will, the invalidity requirement of denying the essential Will and narrative proofs), criticism of the doubts and achievements of the theory (the eternity of Divine agency and the universe of the unity of Divine will, conformity of Divine Will and the system of causality and the impossibility of Badā'(alteration in the divine will)), have been explained and presented.
