“Therefore, since we are receiving a kingdom which cannot be shaken, let us have grace, by which we may serve God acceptably with reverence and godly fear.” – Heb. 12:28

We are receiving an unshakable kingdom.

We should show others unmerited favor.

Through this free kindness we well-pleasingly serve God.

That service is empowered by holy-caution and awe.

The word picture attached to reverence (“godly respect”) is carrying a priceless vase across the room – in a “devout” (respectful) fashion (Robertson).
