A prayer from Ambrose from the devotional book “Be Thou My Vision“
O Lord, you have mercy upon all – take away from me my sins, and mercifully kindle in me the fire of your Holy Spirit. Take away from me the heart of stone, and give me a heart of flesh, a heart to love and adore you, a heart to delight in you, to follow you and to enjoy you, for Christ’s sake.
Amen
