The person I was while praying yesterday is not the person I am while praying today. The Today Me has never prayed before, and I am eager for her to express herself! My prayers are ever new.
And they are spontaneous, so they surprise me. In many ways, I learn more about myself each day when hearing myself pray out loud. Praying out loud is necessary for my personal growth.
Praying out loud is how I get to know God as I get to know myself.
