Dear T.,
One of the biggest problems we all face is resentment, irritation, anger, or jealousy against anyone and everyone.
Peale has a good formula. Say John is irritating you. Say this to yourself:
“May the love of Christ fill my heart. May the love of Christ for… John… flood my soil.”
Why this is so effective is because it is more than just the usual invocation to love your neighbour.
