How do we know that Christ is our only hope of salvation?

Scripture affirms that Jesus Christ is the only one who can provide the righteousness required by God for salvation. In order to ascend to the hill of the Lord, one must possess clean hands and a pure heart, which we do not have by nature. Christ, however, is the only one who has this righteousness, and He obtained it not for Himself, but for His people, granting them access to God through His sacrifice. The grace of God acts in calling His people to come out of false religion and to trust solely in Christ for their salvation.
