Seeds of Doubt
“He [Satan] 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)
Satan loves to plant seeds of doubt into the minds of both believers and nonbelievers alike. Jesus warns in today’s passage that Satan is an old pro at lying, so to speak. He has been at it “from the beginning.”
