How do we know God's calling is effective?

We understand God's calling to be effective based on scriptural assurance that His call results in true repentance and faith. In Genesis 27, the narrative of Jacob fleeing to Laban is not merely an incident but a reflection of God's initiating grace in his life. God’s work in those whom He calls is affirmed by Romans 8:30, which states that those He called, He also justified. The effectiveness of God's calling is seen through the life changes and new heart desires within the believer, a demonstration of His sovereign grace working in their lives.
