All men are made in God's image; but to be in His likeness is granted only to those who through great love have brought their own freedom in subjection to God... Free will is the power of a deiform soul to direct itself by deliberate choice towards whatever it decides.
The more wood you pile on a fire the more heat you get, and thus it is with God - the more you think on Him the more you are fired with love and fervor towards Him. He who loves the Lord is always mindful of Him, and remembrance of God begets prayer.
I wonder at our free will: it is strong, and yet it has been overthrown. It is a master, yet it has become a slave. It has the opportunity to conquer, yet it would rather yield and be conquered itself. Although it is free, it gives itself to slavery, like a bondswoman who signs with her own hand the agreement that binds her.
