"Yet he, being compassionate, atoned for their iniquity and did not destroy them; he restrained his anger often and did not stir up all his wrath.”
There is nothing we can do to reconcile ourselves to God. Our sins are too great. No amount of good deeds can ever restore our broken relationship with God. Instead, we need God to reconcile us. We need God to atone for our sins, and Jesus did just that.
"For while we were still weak, at the right time Christ died for the ungodly. For one will scarcely die for a righteous person—though perhaps for a good person one would dare even to die— but God shows his love for us in that while we were still sinners, Christ died for us. Since, therefore, we have now been justified by his blood, much more shall we be saved by him from the wrath of God. 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. More than that, we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation.”
