You'll NEVER save anybody as there's nothing to save them from.
Besides, both atheists, agnostics, freethinkers on one side and the theists on the other are commiting the same basic folly and that is "preaching to the converted"
The atheist remains an atheist, the agnostic remains unknowing and the Theist still prefers to grovel at the feet of his capricious God.
I have no problem with God anyway. God even MIGHT exist.
The problem is not God, but faith, religion the phony BS contructed and and edifice built of sand by humans.
God may exist. I still see no need for sacrifice, prayer, praise or grovelling like some idiotic slave or dog begging for a bone and hoping not to have God's size 13 boot shoved up poor pooch's ass.
Even if God's existence be proven it's a long long way to Tipperary and to doctrines of virgin births, trinitarian nonsense, or "sin".
I believe in Nature as the Supreme Power, the Ultimate Source of my being. Nature made me. To Nature I'll return.
Nature IS, and is not MADE by anybody. Therefore, Nature has herself the same exact qualities as God minus the repugnant BS contruct of religion.
In fact, those who adore Nature, whether they deify her or not, do so by the practice of science not faith-based constructs of intellectual filth.
If God exists, science will discover Her, or Him or Them.
Faith is nothing but a belief in the ridiculous, the absurd, in that which has NO foundation in reality, NO substantiation, no evidentiary basis, no empirical foundation in reality.
It is nothing but wishful thinking.
If I believe it HARD enough it is true? FALSE
If enough people believe it, it becomes true? FALSE.
If the majority believe it, it is certain? FALSE
If it would be better for us if true, it is true? FALSE
But Christianity more than any other faith takes pride in the utter ridiculousness of their doctrines.
The more idiotic the teaching is, the more faith required, hence the more CERTAIN.
