As Christians, we sometimes face times of spiritual depression—times of trouble, worry, even misery. Dr. Martyn Lloyd-Jones tells us in this sermon that it is profoundly important for us to recognize that the Christian life is a life of spiritual conflict with the powers of evil. As he focuses on Ephesians 6:10-11, he reveals the Christian’s hope: Jesus Christ has conquered our enemy. Since we are in Christ, His mighty power comes into us. We can be strong in the Lord and in the power of His might. It is with that power alone we can triumph and prevail, finding complete victory over the spiritual forces that are arrayed against us.
