How do we know Christ is our wisdom and righteousness?

According to 1 Corinthians 1:30, Christ has been made unto us wisdom, righteousness, sanctification, and redemption. This means that all we need for justification before God and righteous living comes from Him. Jesus is our perfect wisdom, allowing us to know God truly, and our righteousness, providing the necessary covering for our sins. The believer's wisdom and righteousness are not derived from our efforts, but are gifts from God through Christ, highlighting the central role He plays in our salvation and sanctification.
