How do we know that Christ is sufficient for our righteousness?

According to 1 Corinthians 1:30, 'But of Him you are in Christ Jesus, who became for us wisdom from God—and righteousness and sanctification and redemption.' This verse highlights that Christ is our complete righteousness. It is not based on our works but solely on His faithful obedience and sacrifice. Believers who understand this realize that their standing before God is not dependent on their actions but entirely on Christ's perfection. This assurance frees us from self-righteousness and points us to the grace of God for our full acceptance.
