Q 1. When we refer to the Apostolic age, we are referring to the time the Apostles of Christ walked the Earth. Since they all died, the Apostolic period has ended. Q 2. Where does the Bible say everyone will know instantly when they receive the Holy Spirit? Where does it say that everyone who receives the Holy Spirit immediately shows an outward sign to evidence the event? Personally, I prefer when God works through me without my knowledge.
