How do we know election is true in the Reformed view?

The doctrine of election in Reformed theology is rooted in the sovereignty of God, who has chosen His people before the foundation of the world (Ephesians 1:4-5). The evidence of being elected is manifested in genuine faith in Christ. It is not our election that secures our unity with Christ, but our faith in Him. This faith is a gift from God and confirms our identity as chosen ones. The relationship established through Christ reflects that we are heirs according to the promise, thereby affirming God's eternal purpose for salvation.
