“It is written.” Stand upon it, and if the devil were fifty devils in one, he could not overcome you. On the other hand, if you leave “It is written,” Satan knows more about reasoning than you do. He is far older, has studied mankind very thoroughly, and knows all our weak points. Therefore, the contest will be an unequal one. Do not argue with him but wave in his face the banner of God’s Word. Satan cannot endure the infallible truth, for it is death to the falsehood of which he is the father.
