How do we know Christ is the way of righteousness?

In both the Old and New Testaments, Christ is presented as the ultimate fulfillment of righteousness. Psalm 1 references the blessed man, which applies not only to believers but perfectly to Christ himself, who is the embodiment of righteousness. Jesus states in John 14:6, 'I am the way, the truth, and the life,' indicating that He alone provides access to God and is the perfect representative who meets the demands of the law. Therefore, we know Christ is the way of righteousness because He is the mediator through whom we receive God's grace and the righteousness necessary for salvation.
