Why is grace important for Christians according to Zechariah?

The sermon emphasizes that the word ‘grace’ serves as the foundation for understanding God's dealings with His people. In Zechariah 4:7, the prophetic message includes the cry of 'Grace, grace, unto it', indicating that any progress made in the temple’s rebuilding—and by extension, in the believer’s life—comes solely through God's grace. This grace is essential because it reassures believers that their weaknesses, sins, and failures do not hinder God's redemptive plan. It is through grace that Christians are reminded of their reliance on Christ, who laid the foundation and will also complete the work. This concept is central to Reformed theology, which teaches that salvation is all of grace, from beginning to end.
