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, Isa 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.
5. eighth—that is, Noah, and seven others. Contrasted with the densely peopled "world of the ungodly."
preacher—not only "righteous" himself (compare 2Pe 2:8), but also "a preacher of righteousness": adduced by Peter against the licentiousness of the false teachers (2Pe 2:2) who have no prospect before them but destruction, even as it overtook the ungodly world in Noah's days.
