What does the Bible say about salvation before the foundation of the world?

The concept of salvation occurring before the foundation of the world is clearly articulated in Ephesians 1:4-5, which states that believers were chosen in Christ before the world was created. This doctrine affirms that God's purpose in salvation is rooted in His eternal will and grace rather than human efforts. It speaks to God's sovereignty, whereby He elects individuals based on His purpose, demonstrating that salvation is ultimately God's work. These truths align with the Reformed understanding that God has a people in mind from eternity and that His choices are predicated on His own glory.
