He opens the tombs

When you hear that at that time the Lord freed the souls from hell and the regions of darkness and that He descended into hell and did an amazing work, do not think that this does not have any personal meaning for you.

Man, indeed, can readily accept the evil one. Death has its grip on the children of Adam and their thoughts are imprisoned in darkness. And when you hear mention made of tombs, do not at once think only of visible ones. For your heart is a tomb and a sepulcher. When the prince of evil and his angels have built their nest there and have built roads and highways on which the powers of satan walk about inside your mind and in your thoughts, then really, are you not a hell and a sepulcher and a tomb dead to God?

... But the Lord descends into the souls of those who seek Him. He goes into the depths of the hellish heart and there He commands death, saying, "Release those captive souls that seek after Me, those that you hold by force in bondage." He breaks through the heavy stones that cover the soul. He opens the tombs. He truly raises to life the dead person and leads that captive soul forth out of the dark prison.
