Matthew 6:6 But when you pray, go into your room, close the door and pray to your Father, who is unseen. Then your Father, who sees what is done in secret, will reward you.
That reminds me of a story. Every night this mother would kneel on the floor with her little 4 year old to pray. And then one night the little girl asked if she could pray. The mother consented and the little girl began to pray. The more she prayed the softer and softer her little voice became, until her mother could no longer hear her speaking. And then finally the little girl said, Amen! The mom said, Honey, I didn’t hear a word you said. The little girl answered, Mama, I wasn’t talking to you.
