Why is God's grace irresistible?

God’s grace is described as irresistible because it effectively brings about the transformation and response in the heart of the elect. As illustrated in Psalm 65:4, those whom God chooses and calls are enabled by His Holy Spirit to approach Him willingly. This grace illuminates the beauty of Christ to the sinner, compelling them to respond positively to the gospel. Instead of being coerced against their will, the elect find their wills aligned with God's as He revives their hearts and minds, leading them to genuine faith.
