“Let your door stand open to receive him, unlock your soul to him, offer him a welcome in your mind, and then you will see the riches of simplicity, the treasures of peace, the joy of grace. Throw wide the gate of your heart, stand before the sun of the everlasting light that shines on every man… It is the soul that has its door, its gates. Christ comes to this door and knocks; he knocks at these gates. Open to him; he wants to enter, to find his bride waiting and watching.” (St. Ambrose of Milan, Bishop and Doctor of the Church, from An Exposition of Psalm 118)
