God is as equally concerned with what we do as to how we do it. It is not only important that we have the right kind of conversation, but that our conversation be based on “simplicity and godly sincerity.” In other words, our conversation should be genuine and never extravagant. People behave for different reasons. Sometimes those reasons are godly, yet at other times they reflect ungodliness. Anyone can feign a good conversation for a short period; however, only with the Lord's help can one's motives consistently match his actions. Paul not only sought to have his conversation right before the Lord, but also desired a genuine change of heart to bring forth the proper conversation.
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.
