God/Bible says: we should pray secretly for open rewards from God...

God/Bible says: And when you pray, you shall not be as the hypocrites are: for they love to pray standing in the churches and in the corners of the streets, that they may be seen of men. Verily I say unto you, they have their reward [Matthew 6.5] But you, when you pray, enter into your closet, and when you have shut the door, pray to your Father who sees in secret shall reward you openly [Matthew 6.6]  So pray in secret for rewards from Father in heaven. Though we don't see God, He sees us clearly.
