'Our Saviour's meaning, when He said, ye must be born again and become a little child that will enter into the Kingdom of Heaven, is deeper far than is generally believed. It is not only in a careless reliance upon Divine Providence, that we are to become little children, or in the feebleness and shortness of our anger and simplicity of our passions, but in the peace and purity of all our soul. Which purity also is a deeper thing than is commonly apprehended.' (Ill, 5.)
