15 And let the peace of Christ rule in your hearts, to which indeed you were called in the one body. And be thankful. 16 Let the word of Christ[g] dwell in you richly; teach and admonish one another in all wisdom; and with gratitude in your hearts sing psalms, hymns, and spiritual songs to God.[h] 17 And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him. Colossians 3:15-17 (NRSV)
The only way to have the peace of God rule in our hearts is to get the Word in us and let it dwell richly. What does “dwell richly” even mean? Rich means an abundance way beyond more than enough. To get that much Word in us, requires that we spend a lot of time meditating on the Word. Once we have meditated on the Word, it fills our thoughts. That leads us to praising God and having an attitude of gratitude. That is right thinking and that leads to right words and right deeds (actions). We will be able, by the leadership of God’s Holy Spirit, to do everything in His name and for His glory. If we practice doing things in this manner, praise and thanksgiving will become as natural as breathing.
