Dr. David Jeremiah examines the command to be filled with the Spirit in Ephesians 5:18, emphasizing its essential place in the Christian life. He outlines the conditions for experiencing the Spirit’s fullness, including a desire for His control, a turning from sin, a full dedication to Christ, and a daily dependence on the Spirit. He then highlights the resulting expressions of a Spirit-filled life through speaking, singing, giving thanks, and submitting, as described in Ephesians 5:18–21.
