Do not underestimate the value of fame. The instinct to get it is strong in material nature and perhaps it has some great value which could be cashed out here and hereafter.

 King Indradyumna faded from heaven when his fame ran out on earth, when nobody knew whom he was or what he did. He was told by the supernatural people that if he could rekindle his fame, he could resume the stay in heaven. His astral body lowered to the plane in which humans dream. There he questioned people as to if they heard of or recognized him. Eventually he went to Markandeya who could not recall him. The yogi mentioned an elderly crane who mentioned an much elderly owl which mentioned a turtle, all being elder to the other. The turtle remembered the king because the turtle lived in a lake which was dug out by the king a long time ago. Once that turtle stated this, Indradyumna returned to heaven.

 The point is that maybe this preacher has some wealth in the form of fame which would support his stay in heaven for some time to come. He also has tons of piety because of influencing people to tow the moral line as per his Christian beliefs.
