The 4th Luminous Mystery of the Rosary for today is The Proclamation of the Kingdom. Jesus called the Twelve to be his Apostles and they followed him immediately. Just the same Jesus is calling us today. Read the Gospels and you'll hear him calling you. If you don't hear it, then you won't hear it even if he appears today asking you in person. It's not how or when he calls you that matters, it's how you respond to his call.
