Your pain for the other’s lack of faith shows your love of God. You know well that pain is one of the most frequent manifestations of the presence of love.

Be careful so that you don’t hate those who don’t believe. This would be harmful for you and useless for them. Look at them with compassion, as to some travellers that were attacked and robbed by some thieves. Sympathise with them as you do with the poor on the street. Pray to God for them.  Your first rule should be: pray to God for those who have fallen from faith. The grace of Lord be with you!
