The test is this: How do we react when we are betrayed by someone that is close to us, whether it be a family member, friend, close associate or a stranger? Is your first thought, “I should pursue peace with all men”? Or does anger immediately fill you and your mind starts to think about ways to “get even”? What does “get even” mean and how do we know when we are “even”? Ignore the anger? No, it you hold your anger, it will eventually become a “root of bitterness”. That root, as it grows, will push every good thing out of the way to manifest itself in your personality. What then?
18 If possible, so far as it depends on you, be at peace with all men. 19 Never take your own revenge, beloved, but leave room for the wrath of God, for it is written, “Vengeance is Mine, I will repay,” says the Lord. 20 “But if your enemy is hungry, feed him, and if he is thirsty, give him a drink; for in so doing you will heap burning coals on his head.” 21 Do not be overcome by evil, but overcome evil with good. –Romans 12:19-21 (NASB)
Let God handle it for you. Jesus was betrayed by Judas, a “friend” who had been the treasurer of the disciples and a companion for the better part of 3 years. What was his reaction to that betrayal? He allowed Judas to carry out his work even though Jesus knew it would mean His death. Remember, because of our sins, we have all betrayed Jesus and yet, He died for us. Easier said than done, right? So, how do we allow God to do it?
6 Then he said to me, “This is the word of the Lord to Zerubbabel saying, ‘Not by might nor by power, but by My Spirit,’ says the Lord of hosts.–Zechariah 4:6 (NASB)
We listen to the Spirit of the Living God and His Spirit directs us as to what we should say and/or do. Most likely, the only action for us will be to pray for the person who has offended us and prepare our hearts to forgive when we are asked and render assistance and encouragement when the offender needs it.
