How do we know Christ makes us holy?

The notion of being made holy through Christ is central to Reformed theology. In his sermon, the preacher emphasizes that it is through Christ that believers are made holy, as seen in Colossians 1:21-22, which states that Christ reconciles us to God, presenting us as holy and unblameable in His sight. This holiness is not achieved through our works, but through faith in Him alone. God gives His people a new heart characterized by holiness and love for others, and this transformation affirms that our standing before God rests solely on Christ's righteousness.
