I don’t know so much about the bringing of greater good out of particular evils. I tend to look at the big picture of salvation. I also don’t think we should get hung up on the numbers, no matter how small. The way I see this is that it doesn’t matter how few Christians or Catholics there are in Japan. God can do a lot with a little. We don’t know how many souls can be saved through the prayers and sufferings of the faithful there or anywhere else in the world.
For instance, Jesus told St. Faustina that a thousand souls had received graces through her prayers in the moment she was praying. So if so many had received graces in that moment, how many might receive graces over the course of a whole day of praying and offering up our sufferings. Granted, we’re not as holy as St. Faustina but it does make us think about how powerful prayer might just be.
Faustina then says (in paragraph 1783):
“We do not know the number of souls that is ours to save through our prayers and sacrifices; therefore, let us always pray for sinners.”
We can’t know in what ways God will bring a greater good from each bad event. All that we can really concern ourselves with is praying and offering up our sufferings and sacrifices and trusting that the love generated by our prayers and sacrifices will bring the greatest good–salvation to many souls. And from all that I’ve read, it seems that our prayers are even more powerful when we don’t feel warm about our prayer life; that is, when we are in a dry spell. Apparently, when we exercise our will and pray anyway during these periods, even when we don’t feel like it, that is very powerful in the unseen realm.
I like this quote from Fr. Jean C.J. D’Elbee. He talks about this very thing, that is, the small number of Christians compared to the large number of unbelievers and our duty to them through prayer.
He says:
“Some are astonished when they see the number of unbelievers, the number of pagans, the impious and impenitent sinners in the world compared to that of the faithful; there is a surprising disproportion there that is hard to explain. One might wonder whether the Redemption has not failed after all. I think Divine Providence has permitted this (I purposely say permitted and not willed) in order that fervent souls may live the apostolic spirit in a better way, with a greater desire to save unfaithful souls seeing how many there are and that they may share even more the thirst of Jesus on the Cross and his Heart which goes out to the multitude. And then because his chosen souls, his privileged, his elect will love him with a greater love Jesus himself will have mercy on others. You see your responsibility!” – (from p 107 in Consoling the Heart of Jesus)
God Bless you in Japan!
