Sufferings gladly borne for others convert more people than sermons.
Perfect love means putting up with other people's shortcomings, feeling no surprise at their weaknesses, finding encouragement even in the slightest evidence of good qualities in them.
Trying to do good to people without God's help is no easier than making the sun shine at midnight. You discover that you've got to abandon all your own preferences, your own bright ideas, and guide souls along the road our Lord has marked out for them. You mustn't coerce them into some path of your own choosing.
