He must not stop anywhere. "External worship, material worship," say the scriptures, "is the lowest stage; struggling to rise high, mental prayer is the next stage, but the highest stage is when the Lord has been realised." Mark, the same earnest man who is kneeling before the idol tells you, "Him the Sun cannot express, nor the moon, nor the stars, the lightning cannot express Him, nor what we speak of as fire; through Him they shine." But he does not abuse any one's idol or call its worship sin. He recognises in it a necessary stage of life. "The child is father of the man." Would it be right for an old man to say that childhood is a sin or youth a sin?
