i'm a ferm believer in god. i was an atheist a couple of years ago. but in two years time, i've changed a lot. now i'm a yoga practicer, and my life is going great.
the biggest mistake atheists make, in my opinion, is that they say they will believe in God when they will recieve tangible proof. but that's not true faith. belief in God is belief against what your resoning tells you, and without needing any proof.
and for tangible proof, you will recieve a lot of proofs, but only after you start believing.
