Colossians / Question
Colossians says, "Let the peace of Christ rule in your hearts," and connects it to being called in one body Colossians 3:15. The same verse also includes "And be thankful" Colossians 3:15.
In Colossians 3:15–17, the writer gives the community three guiding aims: let Christ’s peace make the deciding call inside them, let Christ’s word live among them in a full and shaping way, and let every action and speech be done under the authority of the Lord Jesus. These verses sit inside the practical turn of Colossians where the writer describes the kind of life that matches their new identity (3:1–4) and contrasts it with old patterns to put off (3:5–11).
These lines present three closely linked influences meant to shape the community’s inner life and shared practices: Christ’s peace, Christ’s word, and the name of the Lord Jesus (verses 15–17). The focus is not only individual spirituality but the life of a gathered group described as “one body” (verse 15).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Colossians 3:15, then read the surrounding section so the answer stays connected to the passage's flow.
15Let the peace of Christ rule in your hearts, to which also you were called in one body. Be thankful.
