“For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. Love worketh no ill to his neighbour: therefore love is the fulfilling of the law.” - Romans 13:9, 10.
Tale-bearing and rash judgement are evidences of lack of love. We should therefore put off these and other vices, by demonstrating love for one another, which the Bible says makes one not to think or do evil to one's neighbour. Loving our fellow man as ourselves means that we will not do to others what we do not want others to do to us. We should not, on the basis of assumptions of hear-say, judge people from afar and pass sentence on them as evil-doers without hearing from them and getting the full details of the matter. It is the character of the devil to present God and His organisation in bad light. He was “a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it”. (John 8:44) Those who will be allowed by God to continue in His organisation are those “that walketh uprightly, and worketh righteousness, and speaketh the truth in his heart. He that backbiteth not with his tongue, nor doeth evil to his neighbour, nor taketh up a reproach against his neighbour... nor taketh reward against the innocent. He that doeth these things shall never be moved.” - Psalm 15:1-5.
