If a person chooses to believe in God isn't hat his/her own choice?
You'd think so wouldn't you... and I'd be perfectly fine with that. But then there's this:
(Matthew 28:19-20) 19 Go therefore and make disciples of people of all the nations, baptizing them in the name of the Father and of the Son and of the holy spirit, 20 teaching them to observe all the things I have commanded YOU. And, look! I am with YOU all the days until the conclusion of the system of things."
Asking an atheist to remain silent while millions of christians spread their ideas is like asking one species to stop reproducing while another takes over the planet.
