Why is God's effectual call important for Christians?

The effectual call of God is vital because, without it, no one would genuinely seek after Him. The Bible describes our natural state as being dead in trespasses and sins (Ephesians 2:1), meaning that we lack the ability to respond to God’s call apart from His sovereign initiative. God’s effectual call not only brings us to awareness of our need for salvation but also actively enables us to respond in faith. The permanence and assurance that comes from an effectual call guarantees that those whom God has called will inevitably come to Him (Romans 8:30). This brings deep assurance to believers that God’s promises of salvation are secure.
