The Greek equivalent of Hebrew shālôm (H7965), denoting not merely the absence of conflict but a state of wholeness, well-being, and restored relationship. It encompasses inner tranquility, interpersonal harmony, peace between nations, and especially peace with God through reconciliation. Used as a greeting (like shalom) and as a theological term for the fruit of the gospel.
Peace in the NT is inseparable from the cross: 'Therefore being justified by faith, we have peace with God through our Lord Jesus Christ' (Rom 5:1). Christ Himself 'is our peace' (Eph 2:14), who broke down the dividing wall between Jew and Gentile, 'making peace through the blood of his cross' (Col 1:20). Jesus bequeaths peace as His parting gift: 'Peace I leave with you, my peace I give unto you: not as the world giveth' (John 14:27) — a peace deeper than circumstantial tranquility. The 'peace of God, which passeth all understanding' (Phil 4:7) guards hearts and minds — an active, garrisoning peace. As a fruit of the Spirit (Gal 5:22), peace is not achieved but received from the Prince of Peace (Isa 9:6).
