False prophets are nothing new.  There were many encounters between the prophets of God and false prophets in the Old Testament, so it should not come as a surprise that those in the early church soon encountered one.  When Barnabas, Saul, and John had gone through Paphos, they found a sorcerer, a false prophet, and a Jew named Barjesus.  We might have to ask how one person could be all three.  Yet, today we have Christians who follow their horoscope as religiously as they do their Bible, if not more so.  You really cannot believe both.  If you follow Christ as your Lord and Master, then you cannot follow His creation, the stars, as the determining factor in your life.  Barjesus was with the deputy of the country, Sergius Paulus, who was said to be a prudent man.  Sergius Paulus called for Barnabas and Saul, because he wanted to hear a word from God.  This must have made Barjesus (Elymas by interpretation) mad.  He withstood Barnabas and Saul, trying to turn the deputy from the faith.  He would have lost a lot of influence if the deputy believed.  If false prophets feel threatened, they will be even more determined to keep people from the truth.  Saul, also called Paul, full of the Holy Spirit, told Elymas what he really was, a man full of all subtility and deceit, a child of the devil, an enemy of all righteousness.  Now, one man can easily be all those things.  Then Paul told him that the hand of the Lord was upon him and he would be blind for a season.  It happened immediately.  God judgment was not deferred.  The deputy believed and was astonished at the doctrine of the Lord.
