What is the effectual calling of God?

Effectual calling refers to the divine summons by the Holy Spirit that enables a chosen sinner to respond positively to the Gospel. Unlike a general call that goes out to all, the effectual call is powerful and specific, resulting in salvation for the elect. As exemplified in the story of Zacchaeus, when Christ calls him by name to come down from the tree, Zacchaeus responds immediately. This underscores the truth that when God purposefully calls someone, that person will respond, as indicated in John 6:44, where Jesus states that no one can come to Him unless the Father draws them. Understanding this doctrine helps believers grasp the certainty of their salvation.
