How do we know that Jesus' blood can cleanse us from sin?

Scripture consistently affirms the power of Jesus' blood to cleanse and justify believers. In 1 John 1:7, it is stated, 'the blood of Jesus Christ his Son cleanses us from all sin.' This truth is foundational in understanding justification and reconciliation with God. The believer's ability to approach God is based on the efficacy of Christ's sacrifice, which removes all sin and offers a reconciled relationship with the Father. When believers contemplate this cleansing, they are filled with hope and encouragement to sing, knowing they are assured of their salvation through Christ’s redemptive work.
