How does the fountain purify from sin and uncleanness?

The cleansing power of the fountain, symbolizing Christ's sacrifice, is rooted in the efficacy of His blood. As indicated in 1 John 1:7, 'the blood of Jesus Christ his Son cleanses us from all sin.' This means that through faith in Christ, believers are washed clean of both the guilt and the stain of sin. Furthermore, as seen in the sermon, this fountain is always open; it is a continuous source of grace, freely accessible to those who come in faith. This transformation is not just an outward change but a profound inward renewal, cleansing the conscience and providing assurance of pardon as believers rest in Christ's redemptive work.
