What does the Bible say about God's election and salvation?

In 2 Thessalonians 2:13, Paul states, 'But we are bound to give thanks always to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth.' This passage highlights the concept of election, emphasizing that salvation is not based on human action or decision, but solely on God's purpose and choice. Throughout Scripture, we see that God's choice is rooted in His eternal love for His people, having predestined them for salvation from before the foundation of the world, as reiterated in Ephesians 1:4-5. Thus, understanding God's election is critical for grasping the entirety of the gospel.
