How does Jesus' sacrifice affect our purity?

The transformative power of Jesus’ sacrifice is foundational for the teaching on purity. In 1 Corinthians 6:11, it is stated, 'But you are washed, but you are sanctified, but you are justified in the name of the Lord Jesus.' This declaration conveys that through Christ’s blood, believers are cleansed from all sin, thus made pure in the sight of God. His sacrifice not only atones for sin but also enables a new identity in Christ, where believers can claim purity despite their ongoing struggles with sin. This reflects a fundamental aspect of Reformed theology, where God’s declaration of righteousness is pivotal to understanding our standing before Him.
