I certainly believe God hears all of our prayers. Whether or not He answers them (as only He can) is another thing.
Correct me if I’m wrong, but do you guys think our prayers for
other people are efficacious for them at all though if we are in the state of mortal sin? Based off my understanding of Church teaching, we are separated from the mystical body of Christ when we commit mortal sin. Thus, one of the resultants is that God’s spirit has left us and we can no longer live a grace-filled life where are prayers and penances are meritorious/efficacious for others and even for ourselves, correct? I think I had read somewhere in a particular Saint’s writings (can’t remember who) where the saint saw people praying, and these people’s guardian angel were making logs/notes of all the peoples prayers, but the one who was in mortal sin, the guardian angel was just looking sad and couldn’t write down anything. Has anybody else heard/read of this? If I find the source of this, I’ll post this later.
I do, think, however, that even though if one is in mortal sin, one can possibly still
receive the grace of repentence/change of heart from someone else praying or doing penances for them. I mean, God wants all men to be saved, right, which I think is why there are many stories of deathbed conversions.
