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 (AMPC)
Peace is the voice of wholeness, safety, wellbeing, true prosperity, and true success.
It’s presence means these qualities are also present. If it’s absent then it means these qualities are also absent.
So whatever you’re thinking, whatever you’re intending, whatever you’re doing, whatever you’re planning, wherever you’re going, whoever you’re dealing with, peace in your heart will tell you with accuracy by it’s presence or absence on the inside of you to either go ahead or stop.
This peace of God is in every believer’s heart.
Discipline yourself always to watch out for, pay attention to, and follow this peace of God in your heart concerning every issue of life.
