Every minister of a congregation in which young people have been brought to the Lord, will remember the keen feeling of anxiety that swept over his heart as he contemplated their entrance on the duties and responsibilities of a public Christian confession. The supreme question at such a time is: How shall these young converts be built up in the knowledge of the truth? How shall they be best taught the real nature of the new life they have received, the dangers by which it is beset, and the directions in which its energy may safely go forth? The desire to give a fitting answer to these questions has given rise to many excellent manuals. In connection with every time of revival, especially, new books for this circle of readers always make their appearance. As Mr. Murray indicates in the Preface, it was in the midst of such a happy period that the following chapters were written. The volume came under my notice whilst I was recently traveling in Holland. A brief inspection showed me that it was one of the most simple, comprehensive, and suggestive of its class.
