Jesus explained the need to make his truth clear to others.

Luke 8:16-18

16 “After people light a lamp, they do not cover it with a basket or put it under a bed. Instead, they put it on a lampstand, so that those who enter their house can see things from its light [MET]. Similarly, you must tell God’s truth to others so that they can know what I can do for them. 17 God wants to make clear all of his truth that was not evident previously. He intends that all of the truth that he had not revealed before be told openly {that his people openly tell others all of the truth that he has not revealed before}. 18 So listen carefully to what I tell you, because God will enable those who accept my truth to understand even more. But God will cause those who do not accept my truth to not understand even the little that they think they have understood.”
