Well, it is one of those obscure, but important teachings of the faith. So important it made the creed which many Christians recite in church every week.
Between his crucifixion and resurrection, Jesus entered hell and released those who were captive there, emptying hell.
This is one of the church’s most powerful words of liberation, release, and healing. We will claim it for our own this week, how God sees us through the darkness into new light.
