What does the Bible say about the election of believers?

The doctrine of election is a vital aspect of Reformed theology, grounded in the belief that God predestines certain individuals for salvation through His sovereign will. Scriptures such as 2 Thessalonians 2:13 affirm that God chose believers from the beginning for salvation, highlighting His mercy rather than any human merit. This doctrine is important because it emphasizes that salvation is an act of grace initiated by God, signifying His authority and love towards His chosen ones. The reality of divine election encourages believers to find security in their relationship with Christ, knowing that their salvation is not dependent on their actions but on God's unchanging purpose and plan.
