prayer for forgotten souls..

i was thinking the other day how there are people out there in the world who are in a lot of pain but have no one to pray for them..Mary, angels, and Saints are praying (and surely their prayers are soo powerful, much more so than mine), but no one on earth. maybe some people feel all alone and like they don't have anyone to turn to, and they don't know God.. i thought of people who are suffering right NOW, at this very moment.. i once read a story in a newspaper about a homeless man who froze to death all alone under a bridge at night. or people who are going through intense physical or emotional pain or are being abused or are feeling very lonely..especially children..

and there are probably souls in purgatory who are forgotten on earth and no one is praying especially for them here.. what if that was me? and how does Jesus feel about all this?
if we knew these people, we could show them God's love through our actions.. but we might not know them, so what can we do..

and then i had this idea, that maybe it's possible to pray something like the Divine Mercy chaplet for "a person who is really suffering right now"; someone we don't know, someone who's maybe on the other side of the world and we'll never meet.. and they might never know we prayed.. but God knows who they are, and maybe because of our prayers He would help them??
i don't know if this makes sense theologically, but it makes sense to me in my heart.
i feel like this idea is from God..

Father please help a person who is most in need right now. i do not know who they are, but You do. You see them and their circumstances and You love them. work a miracle in their life. whatever their suffering is, help them at this moment..rescue them from their sins and have mercy on them.. i feel like my prayer is so weak; "the prayer of a righteous man avails much" but i am not righteous, i lack in both love and humility.. yet Jesus IS love, and He's so humble..look not at my sins but at the merits of Your Son. for the sake of His endless love for these souls and for the sake of His sorrowful Passion on the Cross, please answer this prayer.. i offer His Body and Blood to You in union with all the Masses said throughout the world today for a soul that's in pain right now, and for all the forgotten souls in purgatory. amen.
