Prayer of Thomas a Kempis (1380-1471)
God, our Father, we are exceedingly frail and indisposed to every virtuous and gallant undertaking. Strengthen our weakness, we beseech you, that we may do valiantly in this spiritual war; help us against our own negligence and cowardice, and defend us from the treachery of our unfaithful hearts. for Jesus Christ's sake.
