Peter knew who Jesus is even though Jesus hadn't told him who he is and then asked him to believe him. If Peter's knowledge came from the Holy Spirit and the Holy Spirit is necessary to believe anyway then shouldn't everybody who the Holy Spirit is working on automatically, supernaturally know who Jesus is without being told who he is? I mean today it's totally different. People are told who Jesus is and who the bible says he is and they are asked to believe this. But none of them has the supernatural revelation which Peter had. If the Holy Spirit can simply give you this revelation then why do people even have to be told who Jesus is? Shouldn't everybody automatically know it? What would happen if the people were not told who Jesus said he is and if Jesus also had never said that he is the son of God? Then most likely nobody would even come to the idea of believing that he is the son of God, right? But according to what happened to Peter everybody who the Holy Spirit is working on should simply know it. I wonder how many christians simply knew all of a sudden who Jesus is. If the Holy Spirit simply gives people this knowledge then everybody can be saved even without even having heard about Jesus because the Holy Spirit could simply tell them who Jesus is and then they could get saved. And where did the jews which converted suddenly know who Jesus is? Did God give them this knowledge and others not and only those which he gave this knowledge converted? Why did they suddenly believe in him even though they didn't believe in him before? What was different after the resurrection?
