I will put my laws in their minds and write them on their hearts. I will be their God, and they will be my people.

 Heberews 8:1-13

Now the main point of what we are saying is this: We do have such a high priest, who sat down at the right hand of the throne of the Majesty in heavenand who serves in the sanctuary, the true tabernacle set up by the Lord, not by a mere human being.

They serve at a sanctuary that is a copy and shadow of what is in heaven. This is why Moses was warned when he was about to build the tabernacle: “See to it that you make everything according to the pattern shown you on the mountain.

But in fact the ministry Jesus has received is as superior to theirs as the covenant of which he is mediator is superior to the old one, since the new covenant is established on better promises

The days are coming, declares the Lord, when I will make a new covenant with the people of Israel and with the people of Judah. It will not be like the covenant  I made with their ancestors when I took them by the hand to lead them out of Egypt, because they did not remain faithful to my covenant,

I will put my laws in their minds and write them on their hearts. I will be their God, and they will be my people.

By calling this covenant “new,” he has made the first one obsolete; and what is obsolete and outdated will soon disappear.

Why?

Paul explained the New Covenant real meaning. Because of the Old testment was rejected by Israel, So the Lord made a New covernant through Jesus Christ, and give a new way to God's people. And do not limited to Israel, but more wider to everyone who trust in Jesus and the Lord. No regulation sacrifice not limit on seremoney, but in our heats and our mind with our behavior.

]How?

Who can turn to the Lord is depends on the grace of the Lord,  No because who I am but because He is God, no because what I have done, but because of what He has don4 for us.
