Can a person be assured that they are saved or is salvation something that only God can know? In his sermon on Romans 10:9–10 titled “Assurance of Salvation,” Dr. Martyn Lloyd-Jones answers these questions by bringing the listener to Scripture. In the Bible, the answer is much more gracious and loving than the answers given commonly by people. Salvation is a work of God, not of humans, and how wonderful this truth is. If salvation was dependent on works, no one should have assurance of salvation. Think about how often people fail on the simplest of tasks and how often they let down those who love them most. Yet saving faith is given by God and because this is the case, they can rest in the assurance that God is the author of their salvation. Dr. Lloyd-Jones will show in this sermon on the assurance of salvation that it is the object of the Christian’s faith that gives assurance and it is God’s desire for every Christian to be assured of their salvation. Thank God He does not leave His children in the dark but has given a way to be bold in their salvation.
