Interesting. New to me.
I pray for the salvation of people I encounter and I know a certain percentage of these will probably come to Christ even though I may never see them again on earth.
There was a young boy at my elementary school who was the class bully - a really mean kid. After I was saved and started attending church years later, a young man my age introduced himself to me and said “I know who you are”. It turned out to be that bully all grown up and he was now following the Lord and was totally different.
I found out a few years later he was killed in an accident.
So God had His plan for this fellow and knew the time frame He had on Earth. By His Grace, the man’s life was transformed and then He was called to his Heavenly home.
I didn’t pray for him when he was a young bully but I’ll bet there was somebody who did.
