How do we know election and God's choosing is true?

The doctrine of election is a fundamental aspect of sovereign grace theology, found in passages like Ephesians 1:4-5, which teaches that God chose us in Christ before the foundation of the world. This is not based on foreseen faith or actions, but entirely upon God's sovereign will and purpose. In 2 Thessalonians 2:13, we learn that believers are chosen for salvation through the sanctification of the Spirit and belief in the truth. The assurance in this doctrine lies in its roots within Scripture and its demonstration of God's grace and mercy, affirming that salvation is entirely of the Lord and not of human decision.
