How do we know that God's choice in salvation is true?

The assurance of God's sovereign choice in salvation is clearly articulated in Ephesians 1:4-5, which states that God chose us in Christ before the foundation of the world. This doctrine emphasizes that salvation is not based on human efforts or decisions but solely on God's grace and purpose. Romans 9:15-16 further illustrates this by affirming God's prerogative in dispensing mercy, highlighting that it is not our will but God's will that ultimately saves us. Understanding God's sovereignty deepens our appreciation for grace, reinforcing that our salvation is entirely dependent on His divine choice and not our own merit.
