Hebrews 9:16-17Therefore Christ is the mediator of a new diatheke, so that those who are called may receive the promised eternal inheritance, now that He has died to redeem them from the transgressions committed under the first diatheke. For where a diatheke is, there must also of necessity be the death of the one who made it. For a diatheke is in force after men are dead, since it is of not in force at all while the testator lives.
[diatheke: a will, testament, covenant.]
As will a human will and testament, Hebrews tells us that for the New Covenant to be in force it must first be proved that the one who made it has died.
Who does the Bible say would make the New Covenant with Israel?
Jeremiah 31:31-33“Behold, days are coming,” declares the LORD, “when I will make a new covenant with the house of Israel and with the house of Judah, not like the covenant which I made with their fathers in the day I took them by the hand to bring them out of the land of Egypt, My covenant which they broke, although I was a husband to them,” declares the LORD. “But this is the covenant which I will make with the house of Israel after those days,” declares the LORD, “I will put My law within them and on their heart I will write it. I will be their God and they shall be My people.
Who led Israel out of Egypt and made the Old covenant with them?
Who said He would make a New covenant with Israel, just as He had made the Old?
But the one who makes a covenant has to die for it to be in force.
Is a father's will and testament in force if his son dies?
No. The one who MADE the will must die for his will to be in force.
Therefore, Christ is God.
