We Christians all understand that this has happened, right?
We certainly understand that the lion received sharp teeth and claws, and the rattlesnake received poisonous fangs, and car-sized pieces of metal received sufficient mass to mangle human bodies when in motion. We demonstrate our understanding of these things in how we live our lives, while some people demonstrate their lack of understanding of these things in how their lives end.
Jesus has received dominion. He has received glory. He has received kingship.
These are sure and certain facts. The question for us is, do we demonstrate our understanding of these facts in how we live our lives?
To put it another way: That God allows us to respond freely to the fact of His Son's dominion, glory, and kingship is also a fact. Which fact, then, is more real and present to us in our daily lives: That Jesus is King, or that we can get away, for a time, with living as though He weren't?
