2 Peter 2:7

When God sends destruction on the ungodly, he commands deliverance for the righteous; and, if he rain fire and brimstone on the wicked, he will cover the head of the just, and they shall be hid in the day of his anger. This we have an instance of in his preserving Lot. Here observe, 1. The character given of Lot; he is called a just man; this he was as to the generally prevailing bent of his heart and through the main of his conversation. God does not account men just or unjust from one single act, but from their general course of life. And here is a just man in the midst of a most corrupt and profligate generation universally gone off from all good. He does not follow the multitude to do evil, but in a city of injustice he walks uprightly. 2. The impression the sins of others made upon this righteous man. Though the sinner takes pleasure in his wickedness, it is a grief and vexation to the soul of the righteous. In bad company we cannot escape either guilt or grief. Let the sins of others be a trouble to us, otherwise it will not be possible for us to keep ourselves pure. 3. Here is a particular mention of the duration and continuance of this good man's grief and vexation: it was from day to day. Being accustomed to hear and see their wickedness did not reconcile him to it, nor abate of the horror that was occasioned by it. This is the righteous man whom God preserved from the desolating judgment that destroyed all round about him. From this instance we are taught to argue that God knows how to deliver his people and punish his enemies. It is here presupposed that the righteous must have their temptations and trials. The devil and his instruments will thrust sore at them, that they may fall; and, if we will get to heaven, it must be through many tribulations. It is therefore our duty to reckon upon and prepare for them. Observe here, (1.) The Lord knows those that are his. He has set apart him who is godly for himself; and, if there is but one in five cities, he knows him; and where there is a greater number he cannot be ignorant of nor overlook any one of them. (2.) The wisdom of God is never at a loss about ways and means to deliver his people. They are often utterly at a loss, and can see no way; he can deliver a great many. (3.) The deliverance of the godly is the work of God, that which he concerns himself in, both his wisdom to contrive the way and his power to work out the deliverance out of temptation, to prevent their falling into sin and their being ruined by their troubles. And surely, if he can deliver out of temptation, he could keep from falling into it if he did not see such trials to be necessary. (4.) God makes a very great difference in his dealings with the godly and the wicked. When he saves his people from destruction, he delivers over his enemies to deserved ruin. The unjust has no share in the salvation God works out for the righteous. The wicked are reserved to the day of judgment. Here we see, [1.] There is a day of judgment. God has appointed a day wherein he will judge the world. [2.] The preservation of impenitent sinners is only a reserving of them to the day of the revelation of the righteous judgment of God.
