Salvation brings God's peace to His enemies by transforming them into His allies. However, “the peace of God” mentioned in today's passage involves a daily work in the believer's life. “Peace with God” remains an indissolvable bond, yet experiencing the daily “peace of God” entails an ongoing blessing that may be gained and lost. The “peace of God” comes through prayer and the Bible says this peace is beyond mortal comprehension. It truly comforts a believer’s heart and mind through Christ Jesus. This is why the Lord admonishes believers to “let the peace of God rule in” their hearts (Colossians 3:15). The saved will always be at peace with God, but each Christian must “let” the peace of God work effectually in him on a daily basis.
The New Testament sheds light on two types of peace: peace with God and the peace of God. Peace with God is “through” the Lord Jesus Christ (Romans 5:1; Colossians 1:20). According to today's passage, this “peace with God” is experienced only upon one’s justification at the moment of salvation. Trusting Christ's payment through His death, burial, and resurrection remains the only basis for grasping this peace. Before a man trusts in Christ, he is God's enemy (Romans 5:10), but after salvation, he has been gloriously reconciled to God through the work of God's Son. No man earns this peace and no man can lose this peace to again become God's enemy because this peace is an everlasting peace.
An epistle (Colossians 4:16) is a letter from one person, or a group of people, to another. The epistle of Second Timothy was from Paul to a preacher named Timothy. Timothy was a young man (1 Timothy 4:12) but possessed a strong love for the Lord. Paul testified of this truth repeatedly and today’s passage shows Paul commenting on Timothy’s “unfeigned faith.” There was something refreshingly genuine about Timothy’s walk with the Lord. Though Paul was speaking specifically about Timothy’s faith, he made mention that this faith did not start with Timothy. This faith had been passed from his grandmother Lois to his mother Eunice, and then on to Timothy. In fact, he was being taught scripture from the time he was a child (2 Timothy 3:15). This type of upbringing yielded a young man of “unfeigned faith” who further matured into adulthood with spiritual fortitude worthy of emulation.
Christians in every age have faced varied battles ranging from small skirmishes to life-ending combat. God’s word tells the believer to equip himself as a good soldier of Jesus Christ (2 Timothy 2:3) by putting on “the whole armour of God.” This armour enables those engulfed in the battle to “stand against the wiles of the devil.” The apostle Paul identifies this armour and the importance of every element. Interestingly, as he refers to “the shield of faith,” he suggests taking it “above all.” Faith, though often overlooked, remains a crucial element within the saint’s spiritual arsenal. The Bible drives home this truth by pointing out that the shield of faith can “quench all the fiery darts of the wicked.” Without faith, the believer stands exposed and vulnerable. It is utterly impossible to “be strong in the Lord” apart from a steadfast faith in God and His word. While the sword (the Bible) works on the offense, faith protects and shields.
