Nevertheless I have this against you, that you have left your first love. Remember therefore from where you have fallen; repent and do the first works, or else I will come to you quickly and remove your lampstand from its place--unless you repent. Revelation 2:4, 5, NKJV.
The Redeemer of the world declares that there are greater sins than that for which Sodom and Gomorrah were destroyed. Those who hear the gospel invitation calling sinners to repentance, and heed it not, are more guilty before God than were the dwellers in the vale of Siddim. And still greater sin is theirs who profess to know God and to keep His commandments, yet who deny Christ in their character and their daily life. In the light of the Savior's warning, the fate of Sodom is a solemn admonition, not merely to those who are guilty of outbreaking sin, but to all who are trifling with Heaven-sent light and privileges....
The Savior watches for a response to His offers of love and forgiveness with a more tender compassion than that which moves the heart of an earthly parent to forgive a wayward, suffering son or daughter. He cries after the wanderer, "Return unto me, and I will return unto you" (Malachi 3:7). But if the erring one persistently refuses to heed the voice that calls him or her with pitying, tender love, he or she will at last be left in darkness.
The heart that has long slighted God's mercy becomes hardened in sin and is no longer susceptible to the influence of the grace of God. Fearful will be the doom of that soul of whom the pleading Savior shall finally declare, he "is joined to idols: let him alone" (Hosea 4:17). It will be more tolerable in the day of judgment for the cities of the plain than for those who have known the love of Christ, and yet have turned away to choose the pleasures of a world of sin.
You who are slighting the offers of mercy, think of the long array of figures accumulating against you in the books of heaven; for there is a record kept of the impieties of nations, of families, of individuals. God may bear long while the account goes on, and calls to repentance and offers of pardon may be given; yet a time will come when the account will be full; when the soul's decision has been made; when by a person's own choice one's destiny has been fixed. Then the signal will be given for judgment to be executed.--Patriarchs and Prophets, 165.
