How do we know that our salvation is a result of God's sovereignty?

The sovereignty of God in salvation is highlighted by the fact that it is God who initiates our union with Christ, as affirmed in 1 Corinthians 1:30-31. It is 'of Him' that we are in Christ Jesus, indicating that our inclusion in Christ is entirely an act of God's will. Ephesians 1:4 reinforces this by showing that God chose us in Christ before the foundation of the world. Furthermore, the doctrine of sovereign election asserts that those who are saved are part of God's eternal plan, showcasing His total authority and power over salvation, negating any merit on our part. Thus, our salvation is not based on our own choice but on God's elected purpose.
