Book excerpt: 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. The Secret of Intercession teaches that our lives and faith are strengthened when we persistently pursue God. This one month of daily selections rouses Christians to a right sense of the solemn duty, the high privilege and the wonderful power of intercession. Brief and to the point, Murray writes to foster the spirit of devotion and prayer that is so essential to the Christian life.
