If I do the sins of youth will God choose not to give me knowledge and guidance for myself or for others because I have heard it affects service.
If I am righteous and not just do the righteous act of praying for others does that help others salvation or just make others more holy than one needed to be or have a better life on earth? but is it the praying that makes it so or the righteous living? St John says not to pray for those who commit sin leading to death. Does that mean their sin does not lead to death even if I don't pray for them but it makes their life better?
Does the prayer of a father of confession help his son rise from a fall because he is righteous?
The Psalm says a good understanding have all those who do His commandments. So the more we sin are we further ignorant of all the other things we will have to do to be saved? as Jesus said He who has will be given more but he who does not have even what he seems to have will be taken away from him. And does God want to guide us step by step like the pillar of cloud. The daily bread ? Even if we are saved even if we fall often we won't be as fruitful but we may be sinning too often to not even be saved because even if the distance is small to be saved we may not even walk that distance
