Verse 1
1 Peter 4:1
The Purging Effect of Suffering --
Not all suffering, but in context, the suffering of the righteous.
Christ suffered -- A reference to Christ’s death on the cross and the purpose for which he died, 1 Peter 3:18.
Christ suffered -- Peter introduced this idea in 1 Peter 3:18; he now indicates its significance in Christian experience. In our own physical sufferings, we are to imitate Christ’s attitude (see 1 Peter 2:21-24).
Arm yourself -- pic of a soldier putting on heavy armor
Wuest -- The Greek word translated "arm yourselves" was used of a Greek soldier putting on his armor and taking his weapons. The noun of the same root was used of a heavy-armed foot-soldier who carried a pike and a large shield. The word was used of heavy-armed as against light-armed troops. Peter could have used the latter word. The Holy Spirit selected the former. The Christian needs the heaviest armor he can get, to withstand the attacks of the enemy of his soul.
Arm -- is a military term for putting on heavy armor and preparing for battle. There is a spiritual conflict in our daily lives (cf. Ephesians 6:10 ff; Romans 13:12; 1 Thessalonians 5:8). - Utley
Ceased -- G3973
ceased -- you have finished with sin (or For the one [or One] who has suffered physically has finished with sin): Our suffering with Christ shows that we have identified with him (see Romans 8:17). Those who identify with Christ experience the victory over the power of sin that he won on the cross (Romans 6:1-10). NTLSB
The perfect tense of the verb emphasizes a permanent eternal condition free from sin [because of what Christ did on the cross]. - MSB
Hath ceased from sin. The idea seems to be that of Romans 6:7, “He that is dead is freed from sin. - PNT
ceased from sin -- The main verb can be either MIDDLE (A. T. Robertson’s Word Pictures of the New Testament, p. 121) or PASSIVE (Moulton’s Analytical Greek Lexicon and Barbara and Tim Friberg’s Analytical Greek New Testament). If it is MIDDLE it is encouraging believers to be actively involved in not sinning as followers of Christ’s example. If PASSIVE it is emphasizing the spiritual fact of the believer’s deliverance from the power of sin.
Death annuls one’s relationship to sin. This may be connected to the theological concepts of Rom. 6. Death to the old life brings potential service to God (cf. Romans 6:2-7) or baptism symbolizes one’s newness of life (cf. Romans 6:4; Colossians 2:12).
The whole point is that as believers follow Christ’s example of suffering, so too, His example of victory over sin. We are new creatures in Christ! We must live like it. Christlikeness is the will of God (cf. Romans 8:29; Galatians 4:14; Ephesians 1:4; Ephesians 2:10). It reflects the fact that the image of God lost in the Fall (cf. Gen. 3) is fully restored in Christ. Christians have a choice again on how they will live. They are no longer slaves of sin! Walk in Him! - Utley
