The peace of the celestial city is the perfectly ordered and harmonious enjoyment of God, and of one another in God. (City of God, Book 19)

Is any man skillful enough to have fashioned himself?

Narrow is the mansion of my soul; enlarge Thou it, that Thou mayest enter in. It is ruinous; repair Thou it. It has that within which must offend Thine eyes; I confess and know it. But who shall cleanse it? or to whom should I cry, save Thee? Lord, cleanse me from my secret faults, and spare Thy servant from the power of the enemy. I believe, and therefore do I speak.

There can only be two basic loves... the love of God unto the forgetfulness of self, or the love of self unto the forgetfulness and denial of God.

... the earthly city glories in itself, the Heavenly City glories in the Lord.

Thou hast made us for thyself, O Lord, and our heart is restless until it finds its rest in thee.
