Why is effective grace important for salvation?

Effectual grace is foundational in understanding salvation in sovereign grace theology. It is the grace that effectively brings about the salvation of God's elect, ensuring they will come to faith in Christ. This concept unfolds in Zechariah 3, where Joshua, despite being dirty and condemned, is plucked from the fire and cleansed. Similarly, we are spiritually dead in our sins, yet God's grace reaches us, transforming us and bringing us to faith. Without effectual grace, no one could come to salvation, as all are dead in trespasses and sins, and cannot choose God without His enabling grace.
