“And when thou prayest, thou shalt not be as the hypocrites are: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward.”
KJV, Matthew 6:5
Jesus said that what he told His disciples in secret they were to speak openly about.
Jesus: “Do men light a candle and put it under a bushel?”
“No, so let your light shine before all men.”
