For while we were still weak, at the right time Christ died for the ungodly. 7 For one will scarcely die for a righteous person—though perhaps for a good person one would dare even to die— 8 but God shows his love for us in that while we were still sinners, Christ died for us. 9 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 (Romans 5:6-11).
Christ showed the highest form of love for us by dying for us when we were at our absolute worst–ungodly, evil, deceptive of heart and straight out enemies of God. So if he loved us that much when he died for us, how much more will we be the focus of his affection when our hearts are made right with him?
It means we rejoice in being reconciled to him by his death. But even better, we also get the joy of reconciliation in his life!
