We know God saves sinners because the Bible proclaims it, specifically in Romans 10:13, stating that everyone who calls on the name of the Lord will be saved.
The assurance that God saves sinners is rooted in Scripture. Romans 10:13 tells us, 'For everyone who calls on the name of the Lord will be saved.' This promise is contingent on recognizing our complete inability to achieve salvation on our own. The message of sovereign grace teaches that God’s salvation is entirely by His grace through faith in Christ alone. It is by God’s sovereign decree that individuals are drawn to Christ and that the gospel is preached, ensuring that those whom He has chosen will indeed be saved. Those who inquired of the Lord, as Jehoshaphat did, and earnestly seek redemption will find it in the person of Jesus Christ.
