As I navigate my way around the Atheist sites I've come across more and more Ex-Pastors who have now claimed they've become Atheist and or Agnostic. They usually list all there "religious" accomplishments. I was saved as a teenager, I went to the University of Jesus where I was voted most likely to be the best christian ever. I started a Church we were great, we fed the poor, baptized many souls, yadda yadda yadda.
Now if they say they were "saved" that's good enough for me. And We'll find out one day? I am a "once saved, always saved" kinda guy.
But here's something for them to think about, for every Preacher who leaves Christianity for the positive and encouraging future of the Atheist there are people who have been in the Church for years serving, singing, witnessing, teaching etc. that realize they need a savior. My Sister and her family go to a nice church up the road from us. We've gone there a few times when my nieces and nephews were performing or they had something involving food. But the Pastor of that Church had been there Pastor for about 40 years, and his wife just accepted the Lord.(she was probably about 65 years old?) She was very involved and kept real busy doing all the things that Pastor wives do.
Atheists often accuse Christians of going to church because it's comforting, there is singing/entertainment there, a sense of community, things for the kids. I would say "I go to praise God", those other things you mentioned are cool, but if you ain't there to worship your not gonna finish.
To all who have left the church. God throws big ole parties for his "prodigal sons" please come back, we miss you. feeno
