One consideration I have is that, in any religion, if you are praying and submitting to a "higher power", you are, in effect, forming a relationship with said higher power.
And relationships only truly work if there is respect, but also that the individual in place understands how to love and value themselves. Submitting to a "higher power" will become dysfunctional if the methodology operates as a proxy to learning to be ok with oneself and one's place in the world.
One of the things I've heard and always found to be true is that one of the most difficult things to do is to be in isolation when you really don't like yourself as a person. Left to your own thoughts and devices, if you don't like yourself, if you are crippled by your issues or fears, then it's like being in prison.
I believe religion "works" for folks who have found peace within themselves first, then choose said higher power into their lives, I don't think it works very well for those who use said higher power to find that peace to start.
Best chance you have in any relationship is to love and value yourself, to respect yourself and accept who you are and be clear on what you value and where your boundaries lie. Most people don't have that, and when they seek God of any kind, it taints that chance for whatever redemption they are looking for.
If there is a God ( and I don't believe in him, but to each their own), the fear shouldn't be of facing hell in an afterlife. It should be facing hell in this life. Because if you aren't right with you, that's what life becomes, a series of motions going through blood and grind and suffering.
You don't need a lottery ticket to bet on yourself. Encourage people and give them the tools to be excellent in all things and the rest will take care of itself.
