Nowadays, it is common to manufacture a system of religion. Sometimes people with fertile minds examine all types of religions and take a little of this and a little of that to create their own system. By their selection, they are trying to create a system of religion. But religion cannot be selected; it is the law of God. He has created eternal religious principles, principles not transformed by time, self-evident principles that are not subject to our own interpretation. The real business of human life is to know these laws of God and how to apply them.
