In the silence of the heart God speaks. If you face God in prayer and silence, God will speak to you. Then you will know that you are nothing. It is only when you realize your nothingness, your emptiness, that God can fill you with Himself. Souls of prayer are souls of great silence.
When Jesus heard it, He said to them, “Those who are well have no need of a physician, but those who are sick. I did not come to call the righteous, but sinners, to repentance.”
The New King James Version
