Jesus said that the Devil is the Father of Lies. Christians must be sober and alert as the day of the Lord draws near so that we will be able to hear His voice knowing with all of our hearts that we are not being deceived by the evil one.
John 8:44:Ye are of your father the devil, and the lusts of your father ye will do. 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.
