Why is God's calling significant in the life of a Christian?

God's calling is a central theme in scripture that highlights His sovereignty in the redemption of His people. Ephesians 1:4-5 speaks of God's choosing us in Christ before the foundation of the world, indicating that our calling is rooted in His eternal purpose. In Romans 8:28, we are told that all things work together for good to them that love God, to them who are the called according to His purpose. This calling is effective and transformative, as it signifies not just an invitation but a divine summons that changes the believer’s status before God, leading to justification and eventual glorification.
