Have you ever exercised your spirit? As children of God, have you discovered the secret of spiritual growth? The Bible exhorts us: Exercise thyself unto godliness: for bodily exercise is profitable for a little; but godliness is profitable for all things, having promise of the life which now is, and of that which is to come (1 Tim 4.7b-8). Here is a book that will help you to exercise your spirit on the basic lessons of practical Christian living. By faithfully and prayerfully going through these subjects, you will discover the secret to spiritual maturity. To get the best benefit, it is suggested that you take only one lesson a week. Read it, meditate on it, and pray over it till the Holy Spirit brings you into the truth. Thus, you will exercise your spirit over these fifty-two lessons in one year.
