The word rule means absolute power or control over something. In this world, we can allow many things to rule over us. No matter what is said, something rules you. I know some people ruled by anger while others are ruled by pleasure. Some are ruled by anxiety and worry. Others are ruled by doubt or emotions. The list goes on and on. Whatever rules you controls your actions and your attitude.
I have seen many people being depressed, get fired from jobs, or have a huge fight with their spouse because they were ruled by something like fear or anger. Paul speaks of being content in all circumstances. That is not possible when we allow the world to have power over us. The Bible tells us to let the peace from Christ rule. Wow! The peace of Christ. How differently is life when the peace of Christ rules!?!
When the peace of Christ rules, it doesn’t matter our circumstances, we are content. When the peace of Christ rules, doubt is replaced with confidence. When the peace of Christ rules, security and trust reign over past fears and struggles. When the peace of Christ rules, you surely can have the peace beyond understanding. It’s a real thing. It’s a possible thing. It can be yours. The key word in this passage is “let.” Let the peace from Christ rule. How? Surrender. Be intentional. Allow it. Speak it. Breathe it. Own it.
“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] to which as [members of Christ’s] one body you were also called [to live]. And be thankful (appreciative), [giving praise to God always].” – Colossians 3:15 [AMP]
