How do we know God's salvation is sovereign?

The sovereignty of God in salvation is evidenced through scriptures that indicate that it is God who chooses, calls, and saves His people. As stated in Psalm 47:4, 'He shall choose our inheritance for us,' it is God who determines the inheritance and not our own choices that dictate salvation. In Ephesians 1:4-5, we see that God chose us in Christ before the foundation of the world, highlighting the unconditional nature of His saving grace. Thus, it emphasizes that our salvation lies solely in the hands of the sovereign Lord, who is able and willing to save whom He wills.
