How do we know that salvation is by sovereign grace?

The doctrine of sovereign grace emphasizes that salvation is a work of God alone, initiated and completed through Jesus Christ. Romans 1:16-17 states, 'For I am not ashamed of the gospel of Christ, for it is the power of God unto salvation to everyone that believeth.' This passage highlights that it is God's power that enables belief, proving that it is not through human effort but through divine grace that individuals are brought to faith. Additionally, Ephesians 2:8-9 further reinforces this truth, stating that grace is the means by which we are saved, not by works, allowing no room for boasting. In the context of John 10, the concept that 'my sheep hear my voice' implies that those who respond in faith are those chosen by God and drawn to Him by grace.
