From Peacemaker Ministries blog:
Biblical peacemaking should never be understood as a better way for you to win arguments where you’re “right”. It shouldn’t even be understood as a more likely way to get to the truth. One or both of those things may happen, but neither gets to the heart of why we engage in biblical peacemaking. Biblical peacemaking is at its core a recognition that even in the midst of an argument where we have a lot to lose and where our opponent may be entrenched in sin, the most important thing we can do is to bring glory to God through our conduct. It is an act of faith that out of this peacemaking witness, God can do things far beyond upholding the truth or vindicating us, though he will also do both these things eventually. The “thing far beyond” that peacemaking makes possible is redemption–especially of those trapped in sin.

Too pietist for me.
Thanks for your humility.
