Give us, O Lord, a steadfast heart, which no unworthy thought can drag downwards; an unconquered heart, which no tribulation can wear out; an upright heart, which no unworthy purpose may tempt aside. Bestow upon us also, O Lord our God, understanding to know thee, diligence to seek thee, wisdom to find thee, and a faithfulness that may finally embrace thee; through Jesus Christ our Lord.
–Thomas Aquinas
