Quote by R. C. Sproul

“One of the chief functions of miracles in the New Testament, according to the apostolic testimony, was to authenticate agents of revelation, such as the apostles. God attested that these people were speaking His Word by the wonders and the miracles they performed. Such authenticating miracles would have been completely useless if non-agents of revelation could have performed such works. If Satan had the ability to perform true miracles, Nicodenius only could have said, "We know you are sent either from God or from the Devil." It is true that the Bible warns us about "false christs and false prophets" who will perform "signs and wonders" (Mark 13:22). But Satan's so-called miracles are "lying wonders" (2 Thess. 2:9). Satan can perform incredibly clever tricks, but they are not true miracles; they are phony signs because Satan is not God. Satan cannot create something out of nothing; he cannot bring life out of death; he cannot do the things that only God can do.”
