How does God perform the work of cleansing in our hearts?

The work of cleansing in our hearts is accomplished by the Holy Spirit, who applies the sacrificial work of Christ to us. This is highlighted in the washing of regeneration, which signifies the transformative act of God creating a new heart within us. The process involves coming to Christ, our High Priest, who offers Himself as the perfect sacrifice for our sins. By the Holy Spirit, this cleansing is applied to our hearts, enabling us to recognize our leprous condition and leading us to faith in Christ's redemptive work. This dual action of God, both in Christ's work and in the Spirit's application, is vital for true cleansing and transformation.
