Why is the righteousness of Christ important for salvation?

In our fallen state, we are unable to achieve righteousness on our own due to sin. Therefore, the imputed righteousness of Christ is pivotal for our salvation. In Revelation 19:8, we see that the fine linen which represents the righteous acts of the saints is granted to them, signifying that their righteousness comes not from their works but from Christ. His righteousness is imputed to believers, allowing them to be seen as righteous before God. This divine covering is crucial; without it, one cannot enter into the marriage supper of the Lamb, and they would be cast out into darkness. Thus, Christ's righteousness is the sole basis for our acceptance and hope in eternal life.
