In our first two lessons we looked at the
"Behold the days are coming says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah, not like the covenant I made with their fathers when I took them by the hand to lead them out of the land of Egypt, my covenant which they broke, though I was a husband to them, says the Lord. But this is the covenant that I will make with the house of Israel: after those days, says the Lord, I will put my law in their minds and write it on their hearts, and I will be their God and they shall be my people... They shall all know me from the least to the greatest says the Lord, for I will forgive their iniquity and their sins I will remember no more."

The mediator of the old covenant was Moses. The mediator of the new covenant is Jesus Christ the Son of God. He is called "the mediator of a better covenant enacted upon better promises"
One reason why Jesus was the mediator, and not somebody else, is that his was the only blood that could be shed for the forgiveness of sins. However we will come to that matter in our

Jesus said, "I have other sheep who are not of this fold. I must bring them also, and they shall hear my voice, and they shall become one flock with one Shepherd"
The holy nation is now a spiritual and universal kingdom comprised of all believers in Christ
That's why Jesus told his disciples to "Go into all the world and preach the gospel to the whole creation" and that anyone could believe and obey that gospel and be saved
