Satan is the "father of lies" in that he is the original liar. He is the "father" of lies, and, he is such, just as in the same way that Martin Luther is the "father" of the Reformation, and Robert Goddard is the "father" of modern rocketry. Satan, the devil, is a murderer, because, to lie is the same thing as hate, and to hate your brother or sister is to murder them. Satan told the first lie in recorded history to Eve, in the Garden of Eden. After planting seeds of doubt in Eve's mind with a question (Genesis 3:1), he directly contradicts God's Word by telling her, "You will not certainly die" my thought is, who taught them what death was, and who taught them how to die? (Genesis 3:4). With that lie, Satan led Eve to her death; Adam followed, and so have we all. But even in death can we all come back to Christ our King, this is why he said to some, "LET THE DEAD, BURY THE DEAD," we have to be so willing to choose life, we have to be willing to stop listening to the lies of the devil. Lying is Satan's primary weapon against God's children. He uses the tactic of deceit to separate people from their heavenly Father. Some of his more common lies are "there is no God," "God doesn't care about you," "the Bible cannot be trusted," and "your good works will get you into heaven." The apostle Paul tells us that Satan "masquerades as an angel of light" (2 Corinthians 11:14), so that what he says and does sounds good and seems reasonable. But it is nothing more than a false appearance. The main trick is that Satan uses what we know as logic to twist the truth to the point where it sounds right, it feels right, but the Bible does tell us to lean not to our own understanding, it is also stated that, upon getting all of the knowledge and stuff that we need to make it in this life, it says that to make sure, to make certain, that we gather understanding. My mom and I just recently had this conversation; when I was in elementary school, we took something called reading comprehension, this teaches us how to understand what we just read, now, the Bible, teaches us spiritual understanding, but to get it, we have to be willing to read the Bible, for understanding, not reading just to be reading.
