God is the ultimate source of all energy: natural and spiritual. And His principles and established laws are universally and eternally applicable. Advancement in the spiritual dimension of our lives means that we are becoming more and more like our heavenly Father and His Son, the Lord Jesus Christ. Harnessing God’s available spiritual energy is essential to progress in the Christian life. We must have God’s energy to obey His commandments. Salvation, sanctification, and service for Christ require His divine assistance! And the sources for this kind of motivation to move forward are revealed in God’s Word and summarized for us by Dr. Paul Kingsbury in Harnessing Spiritual Energy.
