What is the drink of God's grace described in the sermon?

The sermon contrasts the destructive 'wine of the wrath of her fornication' with the refreshing 'drink of God's grace,' which is identified as the living water offered by Jesus Christ. Revelation 21:6 highlights that God offers this water freely to the thirsty, indicating that spiritual thirst is quenched by the grace and truth found in Christ alone. This metaphor is essential for understanding the sufficiency of Christ's work and how it nourishes and sustains believers in their spiritual journey.
