How do we know that the doctrine of sovereign grace is true?

The doctrine of sovereign grace rests firmly upon the teachings found in the Bible, where it is revealed that God alone is responsible for the work of salvation and illumination in the hearts of mankind. Passages such as 2 Corinthians 4:6 illustrate that it is God who commands light to shine in darkness, highlighting His authority and initiative. This doctrine is further supported by the understanding that fallen humanity, by nature, is spiritually blind and incapable of seeking God without divine intervention. Therefore, the acknowledgment of God's grace as central to salvation is well-rooted in the Scriptures and vital for understanding the nature of our relationship with Him.
