You Are Mistaken

Make no mistake if one chooses to be mean, lie, cheat, kill or slander others for any reason, they do not belong to Christ. No matter how much they go to church

John 8:44

44. You belong to your father, the devil, and you want to carry out your father's desire. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies.
