Galatians 6:1  Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.

2 Timothy 2:24-25  And the servant of the Lord must not strive; but be gentle unto all men, apt to teach, patient, In meekness instructing those that oppose themselves; if God peradventure will give them repentance to the acknowledging of the truth;

Colossians 3:12-14   Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness of mind, meekness, longsuffering; Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye.   And above all these things put on charity, which is the bond of perfectness.

So what is the key element to healthy conflict?  A loud voice, red face, or pointed finger?  No, none of these will aid in restoring relationships; instead God tells us that meekness is the most important attribute when successfully handling conflict.  It is when we are able to address difficult situations with meekness that our conflicts can be successfully resolved  (re-solved).  Conflict for the sake of conflict, without any meekness or solution, is very unhealthy and will never lead to reconciliation.
