Changing Heart is the Best Hope

Prologue

Ezekiel 36:26 NIV
I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh.

One's redemption begins with this change of heart, which only God can do. It's the the new covenant that God initiated through His Son, Christ Jesus.

It's the cornerstone of a true believer's (saint) justification and sanctification.

From a changed heart and a new spirit proceed the best hope for a good and righteous life - a life begotten of God.

God Writes the Laws
On His Saints' Heart
And Put a New Spirit

Hebrews 8:1-8; 10-13 NIV
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 heaven, and who serves in the sanctuary, the true tabernacle set up by the Lord, not by a mere human being.

Every high priest is appointed to offer both gifts and sacrifices, and so it was necessary for this one also to have something to offer. If he were on earth, he would not be a priest, for there are already priests who offer the gifts prescribed by the law. 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.

For if there had been nothing wrong with that first covenant, no place would have been sought for another. But God found fault with the people and said:

This is the covenant I will establish with the people of Israel
after that time, declares the Lord.
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.
No longer will they teach their neighbor,
or say to one another, ‘Know the Lord,’
because they will all know me,
from the least of them to the greatest.
For I will forgive their wickedness
and will remember their sins no more.”

By calling this covenant “new,” he has made the first one obsolete; and what is obsolete and outdated will soon disappear.
