What does the Bible say about sin and its removal?

Sin is described in Scripture as a debt that we cannot repay, and it separates us from God (Romans 3:23). The only means of removing this debt is through faith in Jesus Christ, who sacrificed Himself to atone for our sins. By believing in Him and His redemptive work, we are justified and our sins are blotted out (Isaiah 43:25). Moreover, this faith is not passive; it involves active reliance on Christ for both forgiveness and the power to overcome sin in our daily lives. Romans 5:20 assures us that where sin abounds, grace does much more abound, underscoring the sufficiency of Christ's sacrifice and the hope of living in victory over sin.
