How do we know God's grace is unstoppable?

God's unstoppable grace is vividly depicted in the sermon as flowing from the heart of the Father, sent through Jesus Christ to rescue us from our sinful state. This grace is not limited or contingent upon human actions; instead, it showcases God's initiative in bringing redemption to humanity. Even in our rebellion and ignorance, God's saving grace is actively pursuing us, offering hope, healing, and restoration. The sermon emphasizes that no man can hinder the proclamation of this grace, as it is grounded in God's sovereign will and love for sinners.
