John Chrysostom, on Heb 12:28

“Therefore receiving an immoveable kingdom, we have grace; whereby let us serve, pleasing God, with fear and reverence.”

“"Wherefore we receiving a kingdom which cannot be moved, let us have grace whereby we serve God acceptably with reverence and godly fear." Let us then do all for this, that we may attain that rest, that we may enjoy those good things. Yea, I pray and beseech you, let us be earnest for this. No one builds in a city which is going to fall down. Tell me, I pray you, if any one said that after a year, this city would fall, but such a city not at all, wouldest thou have built in that which was about to fall? So I also now say this, Let us not build in this world; it will fall after a little, and all will be destroyed. But why do I say, It will fall? Before its fall we shall be destroyed, and suffer what is fearful; we shall be removed from them. Why build we upon the sand? Let us build upon the rock: for whatsoever may happen, that building remains impregnable, nothing will be able to destroy it. With good reason. For to all such attacks that region is inaccessible, just as this is accessible. For earthquakes, and fires, and inroad of enemies, take it away from us even while we are alive: and oftentimes destroy us with it.”
