On God's Likeness:

"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 into subjection to God. For only when we do not belong to ourselves do we become like Him Who through love have reconciled us to Himself. No one achieves this unless he persuades his soul not to be distracted by the false glitter of this life."
