Why are we beginning again to tell you all these good things about ourselves? Do we need letters of introduction to you or from you, like some other people?
You show that you are a letter from Christ that he sent through us. This letter is not written with ink but with the Spirit of the living God. It is not written on stone tablets but on human hearts.
He made us able to be servants of a new agreement from himself to his people. It is not an agreement of written laws, but it is of the Spirit. The written law brings death, but the Spirit gives life.
The old agreement that brought death, written with words on stone, came with God's glory. In fact, the face of Moses was so bright with glory (a glory that was ending) that the people of Israel could not continue looking at his face.
This is what I mean: That old agreement judged people guilty of sin, but it had glory. So surely the new agreement that makes people right with God has much greater glory.
We are not like Moses, who put a covering over his face. He covered his face so that the people of Israel would not see it. The glory was disappearing, and Moses did not want them to see it end.
But their minds were closed. And even today, when those people read the writings of the old agreement, that same covering hides the meaning. That covering has not been removed for them. It is taken away only through Christ.
And our faces are not covered. We all show the Lord's glory, and we are being changed to be like him. This change in us brings more and more glory, which comes from the Lord, who is the Spirit.
