Shake it off. That is what we must do at times. Let me tell you about it. When people come at you the wrong way. . . when they lie . . . when they cheat . . .when you must be around them (you see there are times that you cannot rid yourself due to business or other). You must shake it off.
By doing so you are not releasing them but you are releasing the issue to God. Lament and let God take care of the situation. Yeah, I know you want to tell them off, show them who you are-but I promise-God can show them so much better. They don't know who they are dealing with- for real.
However, you must know. You must know who you are and whose you are, and keep on. Your trying to tell them about themselves, that's no good. They know who they are. A liar will be a liar, a cheat will be a cheat until they recognize Truth.
Your actions can point the way to Truth or you can join them in their mess. That's why you must shake it off. Shake it off and watch what God is doing. enough for now.
