What does the Bible say about salvation before the world began?

The Bible teaches that salvation for God's elect was determined in eternity past, as expressed in 2 Timothy 1:9, which states that He saved us and called us not according to our works, but according to His own purpose and grace. This means that our salvation is founded upon God's sovereign will and is not contingent upon our actions or decisions. The concept of being saved 'before the foundation of the world' emphasizes the comprehensive sovereignty of God in the work of redemption, assuring us that His plan is unchangeable and rooted deeply in His eternal purpose.
