Most loving Lord, grant me a steadfast heart which no unworthy desire may drag downards; an unconquered heart which no hardship may wear out; an upright heart which no worthless purpose may ensnare. Impart to me also, O God, the understanding to know you, the diligence to seek you, a way of life to please you, and a faithfulness that may embrace you, through Jesus Christ, my Lord. Amen.
--Saint Thomas Aquinas
