How does the river of life convey God's grace?

The river of life, as portrayed in Revelation, serves as a powerful symbol of God's grace and mercy. It flows from the throne of God and the Lamb, signifying that this grace is entirely divine in origin, uncontaminated by human merit. Believers are invited to partake of this river freely, as its purity ensures that it brings life and healing without any requirements from individuals. This reflects the core of Reformed theology, which teaches that salvation is entirely God's work, grounded in His sovereign will and perfect righteousness.
