Likewise joy ... - It is a principle of human nature that the “recovery” of an object in danger of being lost, affords much more intense joy than the quiet “possession” of many that are safe. This our Saviour illustrated by the case of the lost sheep and of the piece of silver. It might also be illustrated by many other things. Thus we rejoice most in our health when we recover from a dangerous disease; we rejoice over a child rescued from danger or disease more than over those who are in health or safety. We rejoice that property is saved from conflagration or the tempest more than over much more that has not been in danger. This feeling our Lord represents as existing in heaven. “Likewise,” in like manner, or on the same principle, there is joy.
In heaven - Among the angels of God. Compare Luke 15:10. Heavenly beings are thus represented as rejoicing over those who repent on earth. They see the guilt and danger of people; they know what God has done for the race, and they rejoice at the recovery of any from the guilt and ruins of sin.
One sinner - One rebel against God, however great may be his sins or however small. If a sinner, he must perish unless he repents; and they rejoice at his repentance because it recovers him back to the love of God, and because it will save him from eternal death.
That repenteth - See the notes at Matthew 9:13.
Just persons - The word “persons” is not in the original. It means simply “just ones,” or those who have not sinned. The word may refer to angels as well as to people. There are no “just” people on earth who need no repentance, Ecclesiastes 7:20; Psalms 14:2-3; Romans 3:10-18. Our Saviour did not mean to imply that there were any such. He was speaking of what took place “in heaven,” or among “angels,” and of “their” emotions when they contemplate the creatures of God; and he says that “they” rejoiced in the repentance of one “sinner” more than in the holiness of many who had not fallen. We are not to suppose that he meant to teach that there were just ninety-nine holy angels to one sinner. He means merely that they rejoice more over the “repentance” of one sinner than they do over many who have not fallen. By this he vindicated his own conduct. The Jews did not deny the existence of angels. They would not deny that their feelings were proper. If “they” rejoiced in this manner, it was not improper for “him” to show similar joy, and especially to seek their conversion and salvation. If they rejoice also, it shows how desirable is the repentance of a sinner. They know of how much value is an immortal soul. They see what is meant by eternal death; and they do not feel “too much,” or have “too much anxiety” about the soul that can never die. Oh that people saw it as “they” see it! and oh that they would make an effort, such as angels see to be proper, to save their own souls and the souls of others from eternal death!
