What does it mean that God cleansed His people?

The cleansing of God's people refers to the redemptive work accomplished through the sacrifice of Jesus Christ. In Acts 10:15, God tells Peter, 'What God has cleansed, you must not call common.' This emphasizes that God's elect are justified and made righteous in His eyes solely based on Christ's finished work on the cross. This cleansing is not based on human merit or actions but instead on God's grace, as He has chosen to set apart a people for Himself. In Christ, believers are declared righteous and welcomed into a relationship with God, which should lead to a life of gratitude and obedience. This understanding of being cleansed underscores the assurance of salvation and the transformative power of God's grace in the lives of believers.
