Read Rom.5:10. God’s enemies oppose the principles of His kingdom. The fact that those who cling to their sins will eventually experience God’s wrath (Rom. 5:9) indicates His hatred of the sin that destroys people’s lives. Notice it does not say God hates the sinner, just their actions. He loves them so much that He sent Jesus to heal the relationship, to reconcile them to Himself. To reconcile means to bring together two estranged parties. God seeks to reconcile us through Jesus’ work ( see e.g. Col.1:22). 

Reconciliation is a two-sided affair. Paul makes it clear that God has taken all the necessary steps to heal the conflict between Himself and those at war with Him. The second part is for us to accept His offer of both peace and salvation.  

This reconciliation is a two-step process. Firstly, through ‘the death of His Son.’ Notice the past tense – our reconciliation has already been accomplished. Then comes the magnificent “how much more.” Based on the present reality of our reconciliation with God “how much more…shall we be saved through His life!” Here Paul is using the future tense. Christ’s death has already reconciled us, but we will someday be fully saved through His life. 

In short, because of our justification (Rom.5:9) and our reconciliation (v10), our full salvation at the end of time is guaranteed. God will not leave His people in their “half saved” state. Those walking with Him as friends here on earth can look forward with full assurance to walking with Him in the earth made new. We are saved by His life because He was resurrected and that is our guarantee. He has “the keys of death and hades” (the grave) Rev.1:18 NASB. Rom.8:34 also highlights His intercessory ministry on our behalf in the heavenly sanctuary. As Christians, we long for the fulfillment of the “how much more.”  

The natural response to our acceptance of the gospel is we rejoice (v11). In Chapter 5 Christians have rejoice in hope(v2), suffering (v3) and now their reconciliation and guaranteed salvation (v10). Having passed from death to life, Christians can’t help but rejoice.
