I'm sorry, I haven't read all the posts, just the beginning ones. I would like to add my two cent worths. No, I don't believe religion will die out. Also, the Gospel won't die out. The Church has been reestablished and it will survive.
However, if the religion suffers, including the Church, it won't so much be because of what those on the outside say, but what we on the inside say. Members of the Church, and other members of different denominations, whether they be Christian or non-Christian, say or do things to bring more damage to their cause than any outside factor can hope to accomplish. Cruel words, (something I can be guilty of, sadly) and terrible actions done by members speak volumes and give fuel to those who become disgruntled. Oh, it's such pressure at times trying to be a good example. I fail on that most of the time. I know I can do more damage, on the inside of the faith, than any negative outside source.
