15:7 Joy shall be - Solemn and festal joy, in heaven - First, in our blessed Lord himself, and then among the angels and spirits of just men, perhaps informed thereof by God himself, or by the angels who ministered to them. Over one sinner - One gross, open, notorious sinner, that repenteth - That is, thoroughly changed in heart and life; more than over ninety and nine just persons - Comparatively just, outwardly blameless: that need not such a repentance - For they need not, cannot repent of the sins which they never committed. The sum is, as a father peculiarly rejoices when an extravagant child, supposed to be utterly lost, comes to a thorough sense of his duty; or as any other person who has recovered what he had given up for gone, has a more sensible satisfaction in it, than in several other things equally valuable, but not in such danger: so do the angels in heaven peculiarly rejoice in the conversion of the most abandoned sinners. Yea, and God himself so readily forgives and receives them, that he may be represented as having part in the joy.

These are no fancies of one in a dream; no ravings of a maniac; no imaginations of one under fascination: it is most true that there is plenty of …

The Lost Silver Piece
But, my dear friends, the three parables recorded in this chapter are not repetitions; they all declare the same main truth, but each one reveals a different phase of it. The three parables are three sides of a vast pyramid of gospel doctrine, but there is a distinct inscription upon each. Not only in the similitude, but also in the teaching covered by the similitude, there is variety, progress, enlargement, discrimination. We have only need to read attentively to discover that in this trinity of …

The Turning Point
I. We shall begin by noticing that HERE WAS ACTION--"He arose, and came to his father." He had already been in a state of thoughtfulness; he had come to himself, but now he was to go further, and come to his father. He had considered the past, and weighed it up, and seen the hollowness of all the world's pleasures; he had seen his condition in reference to his father, and his prospects if he remained in the far-off country; he had thought upon what he ought to do, and what would be the probable result …
