Soldier of The Cross, you may not miss a beat because of someone else's sin.
Every day I deal with folks who are upset because someone is making unfair demands, saying something untrue or displaying terrible behavior.
As far as you are concerned, your thought life and behavior must be based on God's Word, what He has done for you, where you are headed, and the fact that you have determined to be a Living Sacrifice.
This is not to imply that you are a wimp. You have a supernatural backbone empowered by the Indwelling Holy Spirit.
Those who are His must have their eyes on Him and must be going forward in a straight line - not glaring or staring at the offender.
You can't fix someone else. You can't lend your emotions to the enemy.
Learn to be one who can be trusted in the hardest circumstances, including misunderstanding, persecution and bizarre events.
Look up and move on!
