4 For if God did not spare the angels when they sinned, but cast them into hell and committed them to pits of nether gloom to be kept until the judgment; 5 if he did not spare the ancient world, but preserved Noah, a herald of righteousness, with seven other persons, when he brought a flood upon the world of the ungodly; 6 if by turning the cities of Sodom and Gomor'rah to ashes he condemned them to extinction and made them an example to those who were to be ungodly;

7 and if he rescued righteous Lot, greatly distressed by the licentiousness of the wicked 8 (for by what that righteous man saw and heard as he lived among them, he was vexed in his righteous soul day after day with their lawless deeds), 9 then the Lord knows how to rescue the godly from trial, and to keep the unrighteous under punishment until the day of judgment,

10 and especially those who indulge in the lust of defiling passion and despise authority. Bold and wilful, they are not afraid to revile the glorious ones, 11 whereas angels, though greater in might and power, do not pronounce a reviling judgment upon them before the Lord.

Commentary on 2 Peter 2:1-9

(Read 2 Peter 2:1-9)

Though the way of error is a hurtful way, many are always ready to walk therein. Let us take care we give no occasion to the enemy to blaspheme the holy name whereby we are called, or to speak evil of the way of salvation by Jesus Christ, who is the Way, the Truth, and the Life. These seducers used feigned words, they deceived the hearts of their followers. Such are condemned already, and the wrath of God abides upon them. God's usual method of proceeding is shown by examples. Angels were cast down from all their glory and dignity, for their disobedience. If creatures sin, even in heaven, they must suffer in hell. Sin is the work of darkness, and darkness is the wages of sin. See how God dealt with the old world. The number of offenders no more procures favour, than their quality. If the sin be universal, the punishment shall likewise extend to all. If in a fruitful soil the people abound in sin, God can at once turn a fruitful land into barrenness, and a well-watered country into ashes. No plans or politics can keep off judgments from a sinful people. He who keeps fire and water from hurting his people, Isaiah 43:2, can make either destroy his enemies; they are never safe. When God sends destruction on the ungodly, he commands deliverance for the righteous. In bad company we cannot but get either guilt or grief. Let the sins of others be troubles to us. Yet it is possible for the children of the Lord, living among the most profane, to retain their integrity; there being more power in the grace of Christ, and his dwelling in them, than in the temptations of Satan, or the example of the wicked, with all their terrors or allurements. In our intentions and inclinations to commit sin, we meet with strange hinderances, if we mark them When we intend mischief, God sends many stops to hinder us, as if to say, Take heed what you do. His wisdom and power will surely effect the purposes of his love, and the engagements of his truth; while wicked men often escape suffering here, because they are kept to the day of judgment, to be punished with the devil and his angels.

Commentary on 2 Peter 2:10-16

(Read 2 Peter 2:10-16)

Impure seducers and their abandoned followers, give themselves up to their own fleshly minds. Refusing to bring every thought to the obedience of Christ, they act against God's righteous precepts. They walk after the flesh, they go on in sinful courses, and increase to greater degrees of impurity and wickedness. They also despise those whom God has set in authority over them, and requires them to honour. Outward temporal good things are the wages sinners expect and promise themselves. And none have more cause to tremble, than those who are bold to gratify their sinful lusts, by presuming on the Divine grace and mercy. Many such there have been, and are, who speak lightly of the restraints of God's law, and deem themselves freed from obligations to obey it. Let Christians stand at a distance from such.
