In Warren Wiersbe's Meet Yourself in the Psalms.
In Warren Wiersbe's Meet Yourself in the Psalms, he tells about a frontier town where a horse bolted and ran away with a wagon carrying a little boy. Seeing the child in danger, a young man risked his life to catch the horse and stop the wagon.
The child who was saved grew up to become a lawless man, and one day he stood before a judge to be sentenced for a serious crime. The prisoner recognized the judge as the man who, years before had saved his life; so he pled for mercy on the basis of that experience. But the words from the bench silenced his plea:
"Young man, then I was your savior; today I am your judge, and I must sentence you to be hanged."
One day Jesus Christ will say to rebellious sinners, "During that long day of grace, I was the Savior, and I would have forgiven you. But today I am your Judge. Depart from me, ye cursed, into everlasting fire!"
