According to our resolution so is the rate of our progress, and much diligence is needful for him who would make good progress. For if he who resolveth bravely oftentimes falleth short, how shall it be with him who resolveth rarely or feebly? But manifold causes bring about abandonment of our resolution, yet a trivial omission of holy exercises can hardly be made without some loss to us.
Strive as earnestly as we may, we shall still fall short in manythings. Always should some distinct resolution be made by us; and, most of all, we must strive against those sins which most easily beset us.
If thou canst not be always examining thyself, thou canst at certain seasons, and at least twice in the day, at evening and at morning. In the morning make thy resolves, and in the evening inquire into thy life, how thou hast sped to-day in word, deed, and thought;
All cannot have one exercise, but one suiteth better to this man and another to that. Even for the diversity of season different exercises are needed.
