Romans 5:9-11 Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God. 10 For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life. 11 More than that, we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation.
Therefore refers to what has been established before. Romans 5:8 established the fact of God’s love for us. God loved us so much that while we were guilty of sin, Christ died for us. Therefore, all who have repented of their sin and believed the gospel (Mark 1:15; 1 Corinthians 15:3-4; Romans 10:9) have been justified (“released from the penalty of sin”) by His blood and will be saved from His wrath at the final judgment when all appear before Jesus, the Judge of all mankind (Acts 17:30-31). Jesus’ death on the cross reconciles (“to exchange hostility for a friendly relationship”) us to God. Our sins made us enemies of God, who is just and must punish sin. God’s love for us moved Him to pay the penalty of our sin Himself by His death on the cross.
Since we are reconciled by Christ’s death on the cross, we will be saved by His life, that is, His resurrection from the dead. While Christ’s death freed us from the penalty of sin, His life frees us from the power of sin now (Romans 6:6-7) and the presence of sin when Jesus returns (John 14:1-3). We can live a new life in this sin infected world because Christ rose from the dead and now lives in every believer giving us immeasurably great power (Ephesians 1:13-14, 19-20; 3:20). We also have the hope of being resurrected to live in a new heavens and earth forever free from the presence of sin (1 Corinthians 15:20-23; Revelation 21:1-4).
Our response to what God has done for us through Jesus Christ is rejoicing (exalting). Have you repented of your sin and believed the gospel? If you have, do you comprehend what a great thing God has done for us because He loves us? A sure sign that you comprehend is your rejoicing (exalting) in the reconciliation you have received through the Lord Jesus Christ. Do people see the sign of your rejoicing? Are you sharing the good news of Jesus Christ so the people around you can begin to display the sign of rejoicing in the Lord Jesus Christ?
