To pray is to communicate with God. Prayer is the substance of what is communicated to God
God knows everything. Nothing we say or do is unknown by Him. No thought or intention escapes His attention. Our attitudes, feelings and disposition are fully known by Him. Why then is there a need to pray? What can we communicate that He does not know already? Jesus said:
“your Father knoweth what things ye have need of, before ye ask Him” (Mt. 6:8).
From earliest times there has been a two-way communication between God and man
Prayer is a responding to God’s invitation to communicate. By praying we draw closer to God, He seems more real and we can tell Him what we want and need.
We communicate with others through more than just the spoken word. The written word, facial expression, body posture, and our behaviour, all send messages to those who can see. In the same way, because God’s eyes “are in every place, beholding the evil and the good” (Prov. 15:3), we communicate with Him about our beliefs, our faith, our desires, and our hopes, by our attitude, our response to situations and circumstances, and our behaviour in general. In that way our whole life becomes a communication with God and we “Pray without ceasing” (1 Thess. 5:17 ).

Far more important than bodily position is our mental state before, during and after prayer. The Bible has examples 8 of what appear to be essential attitudes and characteristics for prayer:
