Many Bible passages connect watchfulness and prayer. While preaching sounds the trumpet of alarm in the ears of men, prayer sounds the alarm in the ears of God. As a watchman, each believer has a responsibility to his brother or sister in Christ. While some believers are spiritually sleeping, unaware of their present danger, other believers ought to be standing upon the tower of watchfulness and calling upon the Lord. This was the point of Paul’s teaching in Ephesians 6:18 when he said, “Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints.”
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.
