What is the connection between naming Jesus “Lord” and acknowledging Him as Savior?
Jesus is Lord, and those who refuse Him as Lord cannot use Him as Savior. Everyone who receives Him (Savior) must surrender to His authority (Lord), for to say we receive Christ when in fact we reject His right to reign over us is utter absurdity. It is a futile attempt to hold on to sin with one hand and take Jesus with the other. What kind of salvation is it if we are left in bondage to sin?
This, then, is the gospel we are to proclaim: That Jesus Christ, who is God incarnate, humbled Himself to die on our behalf. Thus He became the sinless sacrifice to pay the penalty of our guilt. He rose from the dead to declare with power that He is Lord over all, and He offers eternal life freely to sinners who will surrender to Him in humble, repentant faith. This gospel promises nothing to the haughty rebel, but for broken, penitent sinners, it graciously offers everything that pertains to life and godliness (2 Peter 1:3).
To give glory to Christ, we must confess Him as Lord. That’s a part of salvation, not a subsequent act. Salvation is a matter of confessing that Christ is God and, therefore, that He is sovereign in your life.
