I do not believe, nor did I write anything saying, that to go on sinning is OK. My point is prayer obtains the Grace to stop sinning. And particularly when someone is despairing (what I assume the OP meant by "fading") Mary is the one to fly to. I defy anyone to show me where the Church teaches differently.
My point was spelled out clearly, and it is very simple. In short,
if one plays games with God they will receive nothing from their prayers. You'll see in all those saints quotes that they are talking about Catholics who go to mass, and even priests, and yet the majority will be lost, why is that? They all do Hail Mary's, yet they are of no avail
because they are not of good will.
Combine what you say and what I say and you have the answer.
Prayer obtains the Grace to stop sinning, if one is sincere. Scarcely any Catholics today are sincere, I doubt that 1% of baptized Catholics will be saved, if that. Read those quotes by the saints and tell me if I am mistaken.
