John Wesley on 1 Corinthians 13:6

Rejoiceth not in iniquity - Yea, weeps at either the sin or folly of even an enemy; takes no pleasure in hearing or in repeating it, but desires it may be forgotten for ever. But rejoiceth in the truth - Bringing forth its proper fruit, holiness of heart and life. Good in general is its glory and joy, wherever diffused in all the world.
