"Let the peace of Christ rule in your hearts..."

"Let the peace of Christ rule in your hearts, to which indeed you were called in one body, and be thankful." Colossians 3:15

What does it mean to you to "let the peace of Christ rule in your heart"?

Some ideas I had were:

• understand that He is in control
• let the peace of Christ cause you contentment and rest in your situation
• know you are one with Him and rest in that
• "be thankful" that He died for you, that He loves you unconditionally, that he has purposed a plan for your life
