Peace, or lack thereof, is often a compass I use to check whether I am in step with God or not. I suppose it is not surprising then that I find this wisdom in Scripture as well ...
Who is wise and understanding among you? By his good conduct let him show his works in the meekness of wisdom. But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth. This is not the wisdom that comes down from above, but is earthly, unspiritual, demonic. For where jealousy and selfish ambition exist, there will be disorder and every vile practice. But the wisdom from above is first pure, then peaceable, gentle, open to reason, full of mercy and good fruits, impartial and sincere. And a harvest of righteousness is sown in peace by those who make peace.
It may be a decision, a trial, a conversation waiting to be had, an e-mail awaiting send, a phone call that needs to be made ... but if it doesn't leave you with peace, stop! Peace is not happiness ... joy ... celebration. Peace, namely His peace, is much deeper. It's contentment in trials, struggles, and challenges.
I've had both conversations in the flesh, and in His Spirit, and the differentiating factor has always been peace. When I do not have it, I often regret my words and actions - when I do have it, I can't recall regret, even if the conversation or decision was a difficult one to make or stand on.
May peace be your guide ... and if you don't have it? Seek it ... pursue it ... our faith is every active.
Keep your tongue from evil and your lips from speaking deceit.Turn away from evil and do good; seek peace and pursue it.
