God already knows what we want and need – the latter, probably far better than we ever will.
He knows Who He is, and how powerful, and how magnificent, generous, kind, just, worthy of praise ….
He is not Tinkerbelle, that He needs our applause to bring Him back from some deathly torpor – for He does not slumber nor sleep.
So what is the purpose of prayer?
My best guess is that its purpose is to help us realize how much we owe Him, how much we need Him, how much He loves us and wants to hear our voices and hearts, and see our downcast or upturned faces – however stained with tears or illuminated with joy – yearning to see Him and hear Him and know His comfort.
Prayer is a gift, you see, that transcends any answer He might give to any request we might pose or any praise we might offer or any thanksgiving we might express. It is our connection with God through His Son, through His very Spirit; our chance to touch God the Father, Creator and King – and for Him to touch us.
A few moments in His lap each day. Or an entire waking lifetime in recognition of His presence.
It’s His gift to us. It’s our gift to Him.
That’s my best guess at the purpose of prayer.
