God didn’t put angels in charge of this business of salvation that we’re dealing with here. It says in Scripture,
What is man and woman that you bother with them;
why take a second look their way?
You made them not quite as high as angels,
bright with Eden’s dawn light;
Then you put them in charge
of your entire handcrafted world.
When God put them in charge of everything, nothing was excluded. But we don’t see it yet, don’t see everything under human jurisdiction. What we do see is Jesus, made “not quite as high as angels,” and then, through the experience of death, crowned so much higher than any angel, with a glory “bright with Eden’s dawn light.” In that death, by God’s grace, he fully experienced death in every person’s place.
