If you believe that, upon death, a person is immediately in heaven (as opposed to sleeping until the Resurrection), then consider that it makes a lot of sense that they would pray for you.When I need pray, I may ask my dad or others to especially pray for me. Do I think that my dad, if he passes on, would be any less inclined to intercede for me? Doesn't Jesus ever live to make intercession?I feel confident that if I were to die, and if I were ABLE TO, I would for sure be praying for folks. I might even have a better understanding of what they are going through, etc.But can you ASK Mary, Peter, your aunt, your dad, etc. to pray for you if you have passed on? Well, yes, you can ASK...but do they hear/know? Maybe. We simply do not know.Now, one more step.... If you want pray, you don't just walk up to anyone on the street and ask for pray. You ask someone whom you believe can pray effectively, who can get a prayer through, as they used to say. Well, you can see why so many would think that Mary had the inside edge on getting prayers answered. Or why the saints/apostles might have an edge, due to their close walk with the Lord in this life. I am NOT saying that we should pray to Mary. I don't (nor the saints/apostles, just to be clear). HOWEVER, if I died, and IF I could know you wanted me to pray for you, etc., I certainly would.
