How do we know that God's people are chosen?

Ephesians 1:4 confirms that God chose us in Christ before the foundation of the world, emphasizing His sovereign grace in selecting a people for Himself. This choice is not based on our merits or actions but solely on God's purpose and grace. It underscores the belief that salvation is not a result of our efforts but a divine act of God, ensuring that all of His chosen people will ultimately hear and respond to the gospel. Understanding this truth instills confidence in believers, assuring us that we are secure in God's everlasting love and plan.
