So, God wants to Reveal to us His mysteries, and because He has so disposed. Man's initiatives, his religious rites, his executions scrutinizing other books, etc., only hinder the process and alienate the person from the divine initiative.
So, there is a process of preparation for exposure to Revelation, but it is not man-made, on the contrary, it is a process developed by God to unveil how worthy a person is to contain His mysteries. Man can do nothing to ensure that God will entrust His Revelation to him. In this whole process we can prove the presence of the mystery of God's love.
