John 16:33 King James Version (KJV) 33 These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world.
When people are speaking bad about you do not have to respond. Your works speak for you. God’s word was given to us that we can have peace not matter what the circumstances. Be of good courage, you will overcome! Let Go and Let God work on your behalf.
