We are all human, and therefore imperfect.
We may try our best to show the character of Christ in all we do, but sometimes we fall short.
Inevitably, we will make mistakes - we will upset, betray, deceive, and hurt one another.
When someone within the body of Christ "trespasses" against you, how you handle the situation is important.
Thankfully, Jesus gives explicit instructions in Matt18:15-17 on how to confront someone who has wronged you.
If you follow this process, then even if the situation is not resolved, you can at least be assured that you handled the confrontation righteously.

1. Show him his fault, just between the two of you.
   Discretion is important! If the problem is between you and a brother or sister in Christ, then keep it between you.
   Don't share it with others or seek "advice" or "prayer" from others before you address that person directly.
   Broadcasting the problem to others creates confusion and we know from 1Cor14:33 that "God is not a God of confusion but of peace...
   " So, be proactive and decisive and address the person who has trespassed against you - and do it in the strictest confidence.
   
2. If he or she will not listen, take one or two others along.
   Only if that one-on-one meeting goes awry, should you bring others into the equation.
   Mutual friends may be able to offer additional wisdom about the problem at hand - just be sure it's godly wisdom! Be wise in who you choose to accompany you.
   They, too, should be "good trees that bring forth good fruit".
   (Matt7:17) Also, their presence serves as witnesses to your willingness to try and work the situation out in a righteous manner.
   Lastly, we know that where two or three gather in the name of Jesus, He is sure to be in the midst.
   (Matt18:20) So, it's an opportunity to usher in the presence of God, which may bring peace to the situation.
   
3. If he or she refuses to listen to them, tell it to the church.
   If the person who has trespassed against you simply refuses to reconcile, then the last attempt at peace is to communicate the problem to the elders or the leadership of your local church.
   The goal here is not to create further chaos, but to bring reformation and reconciliation.
   Church leadership may be able to shed some light on the situation and through respect and impartiality, gain the offender's trust.
   
4. If he refuses to listen even to the church, treat him as you would a pagan or a tax collector.
   In other words, distance yourself from the person who has wronged you.
   You've done all you can to be reconciled and he or she has refused to do so.
   Coercion won't work, so don't try.
   It's best to stay at peace - don't agitate them further.
   However, even though the nature of the friendship/relationship at this point must change, you should still show the fruit of the Spirit when you do come in contact with that person! Treat the person with kindness and love, and still show peace and obviously self-control in any future encounters.
   

You have the right to get angry when you've been offended - that's a natural response.
However, "in your anger, do not sin.
" (Eph4:26) And make sure you don't harbor anger, bitterness or resentment.
Forgiveness is still God's will and He still expects you to love your neighbors as yourself.
It's impossible to go through life on earth without disagreements.
Disappointments and indiscretions will happen.
When they do, make sure you handle them well.
Christ-led confrontation will keep you in right standing with God!
