Part of his classic Secret Series devotionals, Andrew Murray wrote this month-long devotional to emphasize the necessity of daily fellowship with God. He teaches in The Secret of Fellowship that without taking this daily time to come into His presence, feel your weakness and need, and wait upon the Lord, you cannot fully experience the joy and power of God's Holy Spirit in your daily life. Written over a period of five years, The Secret Series books contain a wealth of teaching that is based on Andrew Murray's mature and full experience in Christ. Briefly yet eloquently, Murray teaches that our lives and faith are strengthened when we persistently pursue God. The Secret of Fellowship contains one month of daily selections that emphasize the necessity of daily fellowship with God for a life full of the joy and power of the Holy Spirit.
