Where exactly is the sense of this? I mean some christians seem to like praying on your knees and they even seem to like it when it hurts their knees. Isn't this a bit strange? Once I read a book from a christian who said that he spent a lot of time praying on his knees on the hard concrete and somehow he said it in a way which gave me the impression that he felt like praying and your knees and accepting pain makes your prayers more effective. I think this is really disturbing. I mean if praying on my knees hurts my knees and it's also not good for the blood flow in the legs and can even cause a thrombosis if you remain in this position for a too long time, then why should I do it? I think this is perverse. This looks like God wants us to experience pain and this makes our prayers more effective. I think this is religiousity in its worst form. Where is the difference between praying on your knees and accepting pain and beating your back with a whip? Recently I came a long a site of a christian bookstore and they were selling some kind of wooden seat which allows you to pray in a kneeling position without cutting off the blood flow and without knee pain. When I saw this wooden "thing" I was totally repelled by it. I think that this is somehow perverse and totally religious as if God was all about praying on your knees. What's your stance on this? I really see no justification for this. Sure, you can sometimes simply get on your knees before God but praying on your knees when it hurts your knees is simply sick.
