Definition: The spirit creature who is the chief adversary of Jehovah God and of all who worship the true God. The name Satan was given to him because of his becoming a resister of Jehovah. Satan is also known as the Devil, because he is the foremost slanderer of God. Satan is described as the original serpent, evidently because of his using a serpent in Eden to deceive Eve, and for this reason "serpent" came to signify "deceiver." In the book of Revelation, the symbolism of a devouring dragon is also applied to Satan.so no ,jesus was not the devil because jesus came to earth to do his fathers will ,not to be a resister.
