In 2 Peter 3, the Christians – all God's elect are represented by Peter's audience as His beloved, even when they were dead in trespasses God loved them (Eph 2:1-10) and in love predestined them (Eph 1:3-6). It is for their sake that God is delaying the Parousia of our blessed Savior. God is waiting until the number of His elect is complete then He will send the Savior to judge the world in righteousness.
Commentaries
John MacArthur says the following in the ESV MacArthur Study Bible: [1]
2 Pet. 3:9 not slow. That is, not loitering or late (cf. Gal. 4:4; Titus 2:13; Heb. 6:18; 10:23, 37; Rev. 19:11). patient toward you. “You” is the saved, the people of God. He waits for them to be saved. God has an immense capacity for patience before he breaks forth in judgment (cf. 2 Pet. 3:15; Joel 2:13; Luke 15:20; Rom. 9:22; 1 Pet. 3:15). God endures endless blasphemies against his name, along with rebellion, murders, and the ongoing breaking of his law, waiting patiently while he is calling and redeeming his own. It is not impotence or slackness that delays final judgment; it is patience. not wishing that any should perish. The “any” must refer to those whom the Lord has chosen and will call to complete the redeemed, i.e., the “you.” Since the whole passage is about God’s destroying the wicked, his patience is not so he can save all of them, but so that he can receive all his own. He can’t be waiting for everyone to be saved, since the emphasis is that he will destroy the world and the ungodly. Those who do perish and go to hell, go because they are depraved and worthy only of hell and have rejected the only remedy, Jesus Christ, not because they were created for hell and predetermined to go there. The path to damnation is the path of a non-repentant heart; it is the path of one who rejects the person and provision of Jesus Christ and holds on to sin (cf. Isa. 55:1; Jer. 13:17; Ezek. 18:32; Matt. 11:28; 23:37; Luke 13:3; John 3:16; 8:21, 24; 1 Tim. 2:3–4; Rev. 22:17). all should reach repentance. “All” (cf. “you,” “any”) must refer to all who are God’s people who will come to Christ to make up the full number of the people of God. The reason for the delay in Christ’s coming and the attendant judgments is not because he is slow to keep his promise, or because he wants to judge more of the wicked, or because he is impotent in the face of wickedness. He delays his coming because he is patient and desires the time for his people to repent.
