1 Peter 3:18-19
For Christ also died for sins once for all, the righteous for the unrighteous, that he might bring us to God, being put to death in the flesh but made alive in the spirit; in which he went and preached to the spirits in prison.
When we hear of Jesus that “he came down from heaven” we have this notion this refers only to his Incarnation. He came down, we think, from Heaven to the stable in Bethlehem. But that is only half the story. In reality, he came further and further down, to poverty, to rejection, to pain, betrayal, death, and finally, to the depths of the grave through crucifixion, the very worst form of death Hell ever invented. There is no abyss he has not seen, no depth he has not plumbed. Today, thank the Lord Jesus for coming down so very, very far.
