When believers sing or recite the confession “Jesus is Lord,” we are affirming his absolute supremacy, not only over the physical and moral universe (Matt. 28:18; 1 Pet. 3:22), and not only over human history (Rom. 9:5), not only over all human beings (Acts 10:36; Rom. 10:12), whether living or dead (Rom. 14:9), not only over the church (Eph. 1:22), but also over our own lives as his willing slaves. The simple but crucial point is that the two words “Lord” and “slave,” kyrios and doulos are correlatives,” (Slave of Christ, pg. 90).
May we live the truth of this statement.
