Pray to your Father who is in the secret place

Matthew 6:6
But you, when you pray, go into your room, and when you have shut your door, pray to your Father who is in the secret place; and your Father who sees in secret will reward you openly.

God values our prayer when we prayer to Him, that means there is no reason we need to show others when we pray to God. Just like when we are talking with someone, we don't need to talk in front of other people that we are not directly talking to. To do so would be pretense. And God also values simple childlike prayer as Yshua has thought us, instead of repetitious religious sounding phrases. Finally prayer may include asking things, but those are supposed to be things which are consistent with the will of God, not just things that we want for our personal benefits only.
