2 But who was found good by the Lord, since “Christ died for the ungodly”? He found them all corrupt trees, but to those who “believed in His Name, He gave power to become the sons of God.” Whosoever then now is a good man, that is, a good tree, was found corrupt, and made good. And if when He came He had chosen to root up the corrupt trees, what tree would have remained which did not deserve to be rooted up? But He came first to impart mercy, that He might afterwards exercise judgment, to whom it is said, “I will sing unto You O Lord, of mercy and judgment.” He gave then remission of sins to those who believed in Him, He would not even take account with them of past reckonings. He gave remission of sins, He made them good trees. He delayed the ax, He gave security.
