Here is a masterly study of the inner life by a heart thirsting after God, eager to grasp at least the outskirts of His ways, the abyss of His love for sinners, and the height of His unapproachable majesty–and it was written by a busy pastor in Chicago! The chapters could be summarized in Moses’ prayer, `Show me thy glory,’ or Paul’s exclamation, `O the depth of the riches both of the wisdom and knowledge of God!’ It is theology not of the head but of the heart. The ten chapters are heart searching and the prayers at the close of each are for the closet, not pulpit. It deals with the deep things of God and the riches of His grace. Above all, it has the keynote of sincerity and humility.
