What does the Bible say about letting the peace of God rule in our hearts?

In Colossians 3:15, the Apostle Paul exhorts believers to let 'the peace of God rule in your hearts.' This peace is a gift from Christ, distinct from worldly peace, as it sustains us through tribulations and helps maintain harmony within the body of Christ. The peace of God is rooted in our reconciliation with God through the sacrifice of Jesus, signifying that we are called to live in unity and thankfulness with one another as part of one body, the Church. This ruling peace acts like an arbiter, guiding our reactions and decisions in accordance with God's will, ensuring that we do not succumb to bitterness or unrest.
