How do we know election is true in Reformed theology?

In Reformed theology, the doctrine of election is derived from a careful reading of Scripture that highlights God's sovereign authority in choosing whom He will save. Ephesians 1:4-5 confirms that God chose specific individuals for salvation before the world was created, indicating that election is not based on human merit or foreseen faith but solely on God's grace. Furthermore, Acts 13:48 states that as many as were ordained to eternal life believed, which reinforces the belief that election precedes faith and is integral to understanding God's redemptive plan. This perspective is rooted in the recognition that God's will is ultimately unassailable, and His electing love is a source of assurance for believers.
