"The invited one felt something stronger than himself, stronger than his childhood and youthful dreams, plans and ideals. It's usually a barely noticeable whisper. You need to listen to it well, strain your attention, if you want to hear it. God's voice is never a command. It is a call for free radical choice. By calling, God guarantees his presence as a friendly force and support in temptations, the courage that the called one can give testimony of Him."
