Christ's righteousness covers our sins by being imputed to us through faith, allowing believers to be accepted by God.
Christ's righteousness is essential to the believer's justification, as it is through faith that this righteousness is imputed to those who believe. This means that when God looks at believers, He sees them cloaked in the perfect righteousness of Christ rather than their sinful actions. 2 Corinthians 5:21 illustrates this beautifully: 'For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.' The exchange is not just forgiveness but a complete transformation, where the believer is clothed in His robes of righteousness, establishing an unshakeable security before God that Adam never possessed.
