"In our awkward attempts to love the needy, we discover our own poverty. They may hunger for bread, but we hunger for righteousness. In clothing the naked, we see our own nakedness, our complete lack of virtue. In visiting the prisoner or the sick we discover that we are imprisoned by habits of prideful and judgemental thought; we are sick with selfish passions and desires. When we do the outer work that Jesus speaks of, we discover the inner meaning that Jesus is referring to."
