3. “Let the peace of Christ rule in your hearts, since as members of one body you were called to peace” (Colossians 3:15NIV).
Like forgiving others, letting the peace of Christ rule in our hearts is easier said than done, but not impossible. Doing so calls for a conscious decision to guard our hearts. According to Ephesians 6:16, protecting our hearts requires us to hold up our shield of faith, with which we can extinguish all the flaming arrows of the evil one.
If our arms feel weak, we can follow the example of the disciples and ask Jesus to increase our faith. Growing faith strengthens spiritual muscle and causes us to stand firm. This allows God’s peace to permeate not only our hearts, but our minds also.
