Hebrews 12: 28-29
Heb.12:28 starts with, “Therefore, since we have a Kingdom which cannot be shaken, …” The writer here has been explaining for his audience, which are Hebrew, and know from memory of life experience and history the covenants of Jehovah with Israel. There are seven such covenants ranging from Adam through David, and finally through the prophets an eighth covenant, which Jeremiah has called simply, a New Covenant, Jer. 31:31.
All of the old covenants were performance based, “if you, then I.” Finally Jehovah revealed a covenant which was solely God based, which we understand to be grace, a gift. Jer. 31:33, “I will put my law within them and on their hearts I will write it; and I will be their God and they shall be my people.” Jehovah reiterates this in the prophet Ezekiel 36: 26 ” Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh. I will put my Spirit within you and cause you to walk in my statutes…”
This New Covenant was to be implemented through the sacrifice of the perfect Lamb of God, Jesus the Son of God. So as we understand it, God offered himself, through His son to us for the forgiveness of sin, the gift of everlasting life, and an advocate in this life, the Holy Spirit which indwells all who believe. This is the New Covenant, a spiritual covenant, not commands in the flesh without any enabling to keep those commands, but rather an indwelling desire for Holiness, through the Holy Spirit placed inside us, which also empowers us to obedience and service. His grace supplies all of our needs, for grace is an enabling attribute of Jehovah.
The Kingdom spoken in this passage from Hebrews is now Spiritual, not physical, as compared earlier in the text as Mount Sinai, where Moses received the ten Commandments, to Mount Moriah, where Jerusalem was built, and Jesus was crucified. So we can symbolically see the difference of the physical versus the Spiritual. On the night of the last supper, where Jesus ate with His disciples in the upper room, He said of the bread “this is my body which is broken for you,” and of the wine, “this cup is the New Covenant in my blood..”
Hebrews 12: 28 “Therefore, since we receive a Kingdom which cannot be shaken, let us show gratitude, by which we may offer to God an acceptable service with reverence and awe; for our God is a consuming fire.” This last line of God being a consuming fire is in reference to Mount Sinai, where the entire mountain that Moses ascended, to receive the Commandments, was ablaze. Hebrews 12:18. We don’t have that fear the Israelites had in the wilderness, for the wrath of God has been assuaged by the acceptable sacrifice of Jesus, the very Son of God. Fear is no longer the motivator for obedience for God’s people, but rather the love of God.
Romans 12.1 ” Therefore, I urge you brethren, by the mercies of God to present your bodies a living and holy sacrifice, acceptable to God, which is your reasonable service of worship.”
The love of God was first revealed in the town of Bethlehem, through a virgin, in a manger, to shepherds, who saw an angelic display of God’s glory, and in obedience to their instructions, saw the Son of God.
