This is a manmade idea, not God-made. God is not the Father of one sect; God is the Father of the whole world, and all are entitled to be called his children, whether worthy or unworthy. In fact it is man's attitude toward God and truth which can bring him closer to God, which is the ideal of every soul. If this attitude is not developed, then whatever a man's religion be, he has failed to live it. Therefore what is important in life is to try to live the religion to which one belongs, or that one esteems, or that one believes to be one's religion.
