Spiritual Warfare by Joyce Meyer

And let the peace (soul harmony which comes) from Christ rule (act as umpire continually) in your hearts [deciding and settling with finality all questions that arise in your minds, in that peaceful state] . . . And be thankful (appreciative), [giving praise to God always].
—Colossians 3:15

You are waging spiritual warfare when you give radical praise to God in the midst of your need and lack. When you are thankful to God for all He has done and is doing, you are defeating the enemy. When you hold your peace in the midst of the storm, you are warring with spiritual weapons (see 2 Corinthians 10:4-5).

Jesus said, Peace I leave with you; My [own] peace I now give and bequeath to you... [Stop allowing yourselves to be agitated and disturbed; and do not permit yourselves to be fearful and intimidated and cowardly and unsettled](John 14:27). Jesus has given you peace! Put it on, and wear it everywhere you go.
