A friend recently sent me a link to Rachel Nuwer's "Will religion ever disappear?" at http://www.bbc.com/future/story/20141219-will-religion-ever-disappear, and I recommend it to anyone who is interested in this topic. In short, her answer to the question posed in the title is "NOT LIKELY."
This conclusion will undoubtedly unsettle some folks and disappoint others, but I believe the evidence provided and her analysis of it are sound. Nuwer points out that there is evidence that we (humans) are hard-wired or genetically predisposed by evolution to need God, religion, the supernatural (or whatever other similar term you may wish to plug into the equation).
My friend also pointed out this verse: "He (God) has planted eternity in the human heart, but even so, people cannot see the whole scope of God's work from beginning to end." (Ecclesiastes 3:11, NLT) Christ once said that the gates of hell would never prevail against his church. (Matthew 16:18) Hmmm, I think that Christ and Ms. Nuwer may be right. What do you think?
