I have also recently become quite intrigued by the argument asserting God is a social construct, a form of explaining the world when it appears inexplicable, confusing, and daunting, and a form of comfort when life becomes overwhelming. God may not actually exist in reality, but the social construct provides a significant degree of mental support to millions of people and is thus a valuable idea. I personally find the idea of an existence without God to be a rather empty one, so I can certainly understand this argument.
I'm sure the above paragraphs make me sound as if I am losing my religion or have already lost it. Perhaps. But I feel my belief has improved lately; my desire for actual evidence instead of non-falsifiable arguments has made me think even more deeply about my faith and there are some arguments regarding the life of Jesus and his disciples that I simply cannot dismiss as non-falsifiable. I believe very much in challenging my religion rather than leaving it to stand weakly, without full intellectual commitment. Without full intellectual commitment, I do not feel it has a sufficiently strong foundation to truly stand the test of time. I admit my bias however, in that I want God to exist and Jesus to have been right; I have grown comfortable with Christianity in the last four years as it gives me a sense of purpose and reason. It gives me a reason to bother. If there is no higher purpose to life, I don't think I'd bother.
At the end of the day, I want God to be more than a non-falsifiable social construct to explain and comfort. I want God to be real and immediate. I hope one day I can acquire an affirmation of that.
