The most important philosophical point in religion is that besides all the moral principles and ethics that religion teaches, there is the central theme which can be traced as the nature of life, of spirit, and that is to make the perfect Being intelligible to the limited mind of man. To do this the ideal of God is preached. The central theme of every religion the messengers have brought was the God-ideal, and every one of them has tried his best to make a picture of that ideal, in order that the people of that time could easily grasp it and benefit by it, to fulfil the purpose of spiritual perfection.
