Colossians 3:15 ~ The Amplified Bible
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].
I have a pastor friend named Gregory, he reminds me so much of Jesus. I remember most things he ever said to me. He reminded me once that the kingdom of God in our lives consists of three vital things; First, right standing with God ~ Secondly, the joy of the Lord, and finally God's peace ruling in our hearts. When I am about to make a decision, I prayerfully consider the condition of my heart. If I am not at peace, I wait. I let the Holy Spirit be the umpire in this decision. Now don't get me wrong, I have at times pushed through the lack of peace and I usually find out later why He was telling me to wait. This is a process to learn how to follow that inner guidance. As I have walked this journey with Christ I am getting better at listening and obeying.
If you are like me and have blown it a time or two, here's the good news; today is a new day. Follow peace!
