How do we know that God ordained redemption before time?

The concept of God ordaining redemption before time is foundational in Reformed theology. Galatians teaches that the fullness of time was planned by God, who sent His Son to redeem His people. This doctrine is supported by other scriptural references, such as Ephesians 1:4-5, which indicates that God chose us in Christ before the foundation of the world. Therefore, God's plan for redemption is not a reactive measure; it is part of His eternal decree where He sovereignly determines the means and timing of salvation for His chosen people.
