Galatians 3:20

The Addition Of The Law

¹⁹ What then is [the benefit of] the law of Moses? It was introduced [as part of God's revelation] in order to define what sin was, until the seed [i.e., Jesus] would come, to whom the promise [of never ending life] was made. The law of Moses was ordained through [the medium of] angels and [delivered] through the hand of an intermediary [i.e., Moses]. ²⁰ Now an intermediary does not serve in a situation involving [only] one person. However, God is one [Being]. ²¹ Is the law of Moses contrary to the promises of God? Certainly not! For if there had been a law given which could provide [never ending] life, then a person could be considered right with God by [obeying the requirements of such] a law.

1 Timothy 2:5

For there is one God and one Mediator between God and mankind --- the man Christ Jesus,

Hebrews 8:6

But now Jesus has obtained a ministry that is as far superior [to that of the Levitical priesthood] as the [New] Agreement, of which He is the Mediator, is better [than the old one], because it has been enacted on better promises.

Hebrews 9:15

Therefore, Christ is the Mediator of a New Agreement, so that [all] those people who have been called [by God] can receive the promise of the never ending inheritance. [This is possible because] a death has taken place for the redemption of [people's] sins who lived under the first Agreement.

Hebrews 12:24

and to Jesus, the Mediator of a New Agreement [between God and mankind], and to the sprinkled blood [of Jesus], which says better things [to us] than [the blood of] Abel did. [Note: The contrast seems to be that "Abel's blood called for vengeance and death (See Gen. 4:10) whereas the blood of Christ provides mercy and life"].

Acts 12:20

Now Herod was very angry with the people of Tyre and Sidon [Note: These were seaport cities not under his jurisdiction]. They came to him as a group, having befriended Blastus, an officer of the king [Herod], and tried to arrange a peaceful relationship [with him] because the country was dependant on him for their food supply.

Romans 3:29-30

Or is God the God of the Jews only? Is He not the God of the Gentiles also? Yes, [indeed], of the Gentiles also,

Galatians 3:17

Here is what I am saying: The Agreement originally made by God [with Abraham], with its attending promises, was not canceled when the law of Moses was given some four hundred and thirty years later.
