Avicenna explains theology on the basis of Ontology, and so presents an ontological argument to prove the existence of God. Avicenna’s important philosophical principle is the distinction between existence and essence. Based on the distinction, beings are divided into two kinds: necessary and possible. The distinction between existence and essence is meaningless for necessary beings, this distinctions is just dedicated to possible beings. The question is that what image Avicenna has of God? What concept of God he enjoys?
Avicenna's concept of God is expressed in two expressions: ‘God is pure existence’ and ‘the essence of God is his existence’. The important question is that what differences there are between these two claims? Is there any contradiction to which Avicenna may be committed in arguing for God’s pure existence on one hand and talking about the unification of his existence and his essence on the other hand? In this article, examining the two expressions we are going to solve the problem and dong so we take advantage of the analysis of Necessary Being’s features.
