How does God effectually call people to salvation?

The effectual calling of God is a crucial doctrine in Reformed theology, asserting that when the gospel is proclaimed, the Holy Spirit works in the hearts of the elect to bring them to faith and repentance. This is not a passive hearing; instead, God impresses His truth upon the hearts of those He has chosen. The sermon cites examples such as the Ethiopian eunuch, who, despite being well-versed in religion, needed Philip to explain the gospel clearly for him to understand Christ. This illustrates God’s purpose in sovereignly ensuring that His people hear and respond to the gospel.
