I think, certainly in the UK, people see Christianity as a form of life insurance, something that old people turn to in order to feel safe for their future. People have a very traditional view of what it means to be a Christian, and what church is like and see it is somewhere to go to when your mind is slowly deteriorating that gives comfort and peace in those final years. It is true that this aspect of Christianity exists, this is undeniable, but anyone who takes any of the teachings seriously will tell you that faith in the Christian God is far more complex, and far more relational than just a get-out-of-jail-free card.
People make snap judgments about almost everything, it’s a perfectly logical natural instinct that prevents you from coming into contact with the same bad thing twice and, equally, leads you to do something pleasurable again and again until you lose interest. I am of course making an overgeneralisation and oversimplification of something that’s influenced by a number of other factors but the principle remains. I know this because I do it myself all the time, we just can’t help it. A good way of testing this point on unsuspecting individuals, provided they are in a talkative mood, is to ask them about their recent holiday destinations, provided they’ve recently been on holiday. You’ll find people saying things like “Oh yes! ‘insert-country-here’ is a lovely country, beautiful scenery, the food’s not too great though,” despite having visited the capital city for just four days, eating at the hotel restaurant every night and visiting two museums and a temple.
