The power of virtue and religious discipline.
You and I, especially I, are nothing and the burden of our sins and our wretchedness warns us sufficiently that we must never be proud of being effective for God’s work. However, when I think of the past, when I see what poor weak men like us have achieved in the world by the power of virtue and religious discipline, I cannot avoid thinking that if you imitate their example, you will receive similar blessings.
