I have a co-worker who grew up in the Middle East. As you may see where this is going he is Muslim. He's a great guy from the pure standpoint of being a human, we get along fine with one another. The other day he happened to mention that when he sees people just reading the Bible anywhere say at a break on work that it bothers him. This is because that in order for him to read the Quran he must cleanse himself first. How terrible it would be if I could not have the comfort of reading the word whenever I felt the need. Thankfully we have a God who has made us free from such rules of law.
In Mere Christianity C.S. Lewis states that one reason people like man-made religion is that they are simple to follow. That Christianity is too complicated for anyone to want to follow. God did not make himself to be figured out in some simple steps, but rather that he is something which is in each one of us and will still never fully be in our understanding. There are some things that the Father does not want us to know. That is why we put our trust in him. Bringing us to the statement that Father knows best. If anything doesn't make sense here let me know, it's late and I'm not sure that I am thinking or typing at my full capacity.
