2:17-22 The word of truth is the water of life, which refreshes the souls that receive it; but deceivers spread and promote error, and are set forth as empty, because there is no truth in them. As clouds hinder the light of the sun, so do these darken counsel by words wherein there is no truth. Seeing that these men increase darkness in this world, it is very just that the mist ofdarkness should be their portion in the next. In the midst of their talk of liberty, these men are the vilest slaves; their own lusts gain a complete victory over them, and they are actually in bondage. When men are entangled, they are easily overcome; therefore Christians should keep close to the word of God, and watch against all who seek to bewilder them. A state of apostacy is worse than a state of ignorance. To bring an evil report upon the good way of God, and a false charge against the way of truth, must expose to the heaviest condemnation. How dreadful is the state here described! Yet though such a case is deplorable, it is not utterly hopeless; the leper may be made clean, and even the dead may be raised. Is thy backsliding a grief to thee? Believe in the Lord Jesus, and thou shalt be saved.
19. promise … liberty—(Christian)—These promises are instances of their "great swelling words" (2Pe 2:18). The liberty which they propose is such as fears not Satan, nor loathes the flesh. Pauline language, adopted by Peter here, and 1Pe 2:16; see on 1Pe 2:16; (compare 2Pe 3:15; Ro 6:16-22; 8:15, 21; Ga 5:1, 13; compare Joh 8:34).
corruption—(See on 2Pe 2:12); "destroyed … perish … corruption."
