Give me, O Lord, a steadfast heart

Thomas Aquinas (1225-74)

Give me, 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 me also,
O Lord my God,
understanding to know thee
diligence to seek thee,
wisdom to find thee,
and a faithfulness that may finally embrace thee;
through Jesus Chris our Lord.
