Galatians 3:22

Galatians 3:22. But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.

All of us, by nature are shut up like criminals in a prison that is so securely bolted and barred that there is no hope of escape for any who are immured within it. But why are all the doors shut and fastened? Why in order that Christ may come and open the one only eternal door of salvation: "that the promise by faith of Jesus Christ might be given to them that believes."
