How does the doctrine of election provide comfort to believers?

The doctrine of election is a core component of Reformed theology, illustrating that God has chosen His people for salvation from before the foundation of the world. In 2 Thessalonians 2:13, Paul writes that God has from the beginning chosen believers to salvation through the sanctification of the Spirit and belief in truth. This doctrine provides profound comfort to believers as it affirms that their faith is not based on their efforts but is a result of God's design and grace, ensuring that His purpose will prevail and that they are secure in their salvation.
