How does surrender to God grow from speech to mind and body?
Surrender begins with speech and reaches the heart
Surrender starts with speech, when your talk turns from worldly chatter to God. Then it settles in the heart and the mind's thoughts begin to join with God.
"O Lord, I am in Your refuge" is surrender of speech; then it descends into the heart, and that is surrender of the mind.
