King James Bible
"And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus."
This refers to a divine tranquility that originates from God Himself, not from circumstances or human effort. Paul presents this as the direct result of the prayer and thanksgiving mentioned in verse 6, emphasizing that this peace is both a gift and a possession of God. This peace transcends human comprehension and logic—it cannot be fully explained or produced by rational thought. The phrase suggests believers can experience profound calm even when circumstances would naturally produce anxiety, defying worldly wisdom. The Greek word for 'keep' (phroureo) is a military term meaning to guard or garrison, picturing God's peace as a sentinel protecting both emotions (hearts) and thoughts (minds) from anxiety's assault. This promise assures comprehensive protection of one's inner life. Christ is the mediator and sphere through whom this divine peace operates, indicating that this supernatural tranquility is exclusively available within relationship with Him. This concluding phrase anchors the entire promise in the person and work of Jesus rather than in human achievement.
