He said unto him, I am a prophet also as thou art; and an angel spake unto me by the word of the Lord, saying, Bring him back with thee into thine house, that he may eat bread and drink water. But he lied unto him. (1 Kings 13:18)
Satan is a liar and deceiver, and should be recognized by the children of God by means of his deceptive wiles.
An angel spake.
Perhaps, but if so it must have been an evil angel that spoke. When God had forbidden man to eat of the tree of knowledge of good and evil under pain of death, the serpent came with the contradictory message, “Ye shall not surely die” (Gen. 3:4). The words of the false prophet identified their source. The true prophet should have known that if he himself had indeed been sent by the Lord, then the angel that spoke through the prophet of Bethel was a messenger of Satan.
A prophet also.
He was, but not God’s prophet. the Lord never sends contradictory messages by His prophets.
