Why is the concept of God's promises before creation important for Christians?

The belief that God made promises before creation is critical for Christians as it underscores the certainty of God's eternal plan. By recognizing that everything was ordained by Him, believers understand that their salvation and all of history are part of a divine narrative with a predetermined outcome. This truth provides comfort and peace amid life's uncertainties, reinforcing that nothing occurs outside of God's purpose. The scriptures attest to this, as seen in passages like Ephesians 1:4, which expresses that believers are chosen in Christ before the foundation of the world.
