How do we know the doctrine of God's sovereignty in salvation is true?

Ephesians 1:4-5 provides a foundational understanding of God's sovereignty in salvation, revealing that He chose us in Christ before the foundation of the world. This highlights God's initiative and plan in salvation, controlling all events according to His will. Throughout Scripture, the sovereignty of God is evident in His governance of the world, His promises, and His ability to accomplish His purposes unimpeded by human actions. The sovereignty is essential to the assurance of salvation because if it were dependent on our actions, there would be no certainty. Rather, it rests in the hands of a God who is faithful and immutable.
