PEACE (שָׁלוֹם, shalom; εἰρήνη, eirēnē). A pervasive concept in the Bible that most commonly relates to a relationship of love and loyalty with God and one another.
In the Old Testament, “peace” carries the fundamental meaning of welfare, prosperity, or wholeness as well as the absence of hostility (compare Westermann, “Peace [Shalom],” 20, 44–53). The term is frequently used as the antithesis of harm (רָעָה, ra'ah; compare 1 Sam 20:7; Jer 29:11; 38:4) and as a synonym for what is good (טוֹב, tov; Deut 23:6; Ezra 9:12; Jer 33:9).
Peace in Greetings and Farewells
The biblical characters use the term “peace” in friendly greetings and farewell statements to communicate an absence of hostility. For example, when his brothers are unsure whether he will exact retribution on them for having extra money in their sacks, Joseph assures them of his friendly disposition toward them by stating, “Peace to you; do not fear”
In the Old Testament, the term “peace” is often used to describe a relationship characterized by friendship, care, loyalty, and love. These relationships can be with God or between people. A close friend in the Old Testament is commonly called “a man of my peace” (Pss 7:4; 41:9; Jer 20:10; 38:22; Obad 7)
Covenant of Peace
Peace with God and one another is fundamental to the promises of Israel’s restoration and the new creation. Isaiah 32:15–18 promises that when the Spirit, who is the sign of the new age, is poured out, He will create righteousness and peace. God has future plans of peace for His people (Jer 29:11); peace will characterize the new temple (Hag 2:9) and Jerusalem (Jer 33:9), whose inhabitants will “love truth and peace” (Zech 8:19). In the Genesis creation account, the narrative revolves around the notion of peace—the creation and maintenance of order and the reversal of disorder
The most prevalent nuance to the concept of peace in the New Testament is the messianic peace accomplished by Christ and experienced by the Church (compare Acts 9:31). In the Old Testament, the concept of messianic peace referred to both the absence of hostilities and a reconciled relationship with God and others in the context of the new creation. This messianic peace comes to fruition in the New Testament in Jesus’ ministry
Jesus achieved messianic peace by means of His death on the cross, which reconciled people to God and one another
