"Proof of divine concealment" is one of the proofs that from the point of view of some philosophers who do not believe in God, including Schellenberg, which is its main principle, is considered an effective reason for denying the existence of God. This argument tries to negate it by relying on monotheistic religions' understanding of some important attributes of God, especially God's complete and absolute love. It is clear that extracting the conceptual foundations of this argument and basically any other scientific problem is an important and long step in understanding it better and also achieving a more complete and comprehensive critique of it. Based on the findings of the previous research, which was carried out by using the descriptive-analytical method and with a critical approach, the special concept that Schellenberg considered of divine love and Also, another concept called "reasonable or irresistible disbelief" are two important conceptual sources of the proof of divine concealment according to him. The extraction and explanation of these two from Schellenberg's point of view, along with some considerations regarding them and showing their epistemological inefficiency in line with the purpose of the proof of concealment, will be presented in this research.
