There are drug addicts changed their destructive lives after believing in Jesus, the testified that Jesus Love touched their hearts and changed their persons!
I was a christian and a drug addict. Atheism changed my life for the better.
Not god, no saint, no angel changed me, I did it all on my own. From crack addiction, alcoholism, pot head, for 19 years, went to church stoned, had many christian friends who got high, etc..I pulled myself out of the rut, without christianity.
If you don't believe me, research me on this forum, I've spoken of this many, many times..
