All you need is love.
I dont care about your opinion. Believe or stop existing, literally there is no hope without. Its in black and white.
I think it's worth noting that your attitude of "I don't care" is contrary to I Peter 3:15, which says to always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have, and to answer with gentleness and respect. I don't understand this stoic attitude that I've seen in Christians who don't care if other people don't believe in God or if other people are saved or not. The biblical command to "love your neighbor as yourself" and "love your enemies," as well as the Great Commission to "go and make disciples of all nations," is clearly contrary to this apathetic attitude that I've seen in most Christians these days.
As far as your last remarks go, I'm not a Christian anymore, and I doubt God's existence, but I strongly disagree that there's no hope without a belief in God. Speaking from personal experience, I'm at peace more now than I ever was during the 31 years I was a devout Christian. That being said, I can't speak for other ex-Christians, who have left Christianity as I have. My personal exodus from Christianity is completely anecotdal, and it may not be true for anyone else who has also forsaken their Christian faith.
