The saints’ freedom from envy is a wonderful phenomenon. The saints not only did not allow envy to conquer their hearts, but exerted themselves greatly to ensure that their friends be exalted and they themselves debased.
Compunction comes when you consider how much you have grieved God Who is so good, so sweet, so merciful, so kind, and entirely full of love; Who was crucified and suffered everything for us. When you meditate on these things and other things the Lord has suffered, they bring compunction.
The way to attain compunction is an attentive life. ‘The beginning of repentance comes from the fear of God and attention,’ as the holy martyr Boniface says.
