“Wherefore we receiving a kingdom which cannot be moved, let us have grace, whereby we may serve God acceptably with reverence and godly fear:”
King James Version (KJV)
12:28 Therefore let us, receiving - By willing and joyful faith. A kingdom - More glorious than the present heaven and earth. Hold fast the grace, whereby we may serve God - In every thought, word, and work. With reverence - Literally, with shame. Arising from a deep consciousness of our own unworthiness. And godly fear - A tender, jealous fear of offending, arising from a sense of the gracious majesty of God.
Heb 12:28 Wherefore we receiving a kingdom which cannot be moved. We Christians have received a kingdom which cannot be shaken and which is eternal. Let us have grace. Hence should serve God with "reverence and godly fear" since we are called to so high an estate.
