The present article analyzes and compares the idea of divine revelation to justify religious beliefs from the viewpoints of Paul Moser and Mulla Sadra. Moser suggests a kind of moral transformation experience that includes direct cognition and internal experience of self-revelation and God’s unselfish love while he considers mere theoretical reason to be inefficient and emphasizes God’s authority and His attributes and goals as well as the axis of divine revelation. Knowledge-by-presence and direct experience of God in Mulla Sadra’s philosophy which is the only way to access true recognition of God is close to divine revelation. The present article shows that, considering the relationship between love and salvation, and knowledge-by-presence and the practical intellect, in Sadrian belief in God, Moser’s approach is close to Mulla Sadra’s even though the method of argumentation of these two philosophers in representing this type of cognition is not completely the same. Considering the commonalities and differences between Moser and Mulla Sadra in justifying belief in God, it seems possible to revise Moser’s approach with a Sadrian reading with a combination of innate nature arguments and self-knowledge.
