Satan knows Scripture

“‘If You are the Son of God,’ [the devil] said, ‘throw Yourself down. For it is written: “He will command His angels concerning you, and they will lift you up in their hands, so that you will not strike your foot against a stone.”’” Matthew 4:6
Three of the Gospels mention how Jesus was tempted by Satan in the wilderness; two of them (Matthew and Luke) give more detail as to what the specific temptations actually were. In both accounts, Satan begins two of the three temptations with the words, ‘If You are the Son of God’. This is not denial on Satan’s part – He knows that Jesus is the Son of God. Rather, these statements should be translated, ‘Since You are the Son of God’.
We see another interesting and alarming aspect in this particular temptation, where Satan tempts Jesus to reveal His Deity by throwing Himself off the temple. He quotes Scripture to Jesus. We think of Satan as being so anti-God, that he is ignorant of what is written in the Bible. But rather, the opposite is true: he knows the Bible better than most Christians! It is no surprise then, that many people in cults are Scripture-literate, but also misquote it. We need to watch out. Just because someone can quote the Bible, doesn’t mean they are saved. Also, we need to know for ourselves what the Bible says, and what the context of particular passages is, so that we don’t fall into the same trappings. This only comes by immersing yourself in the Word on a regular basis, preferably every day.
