How do we know that salvation is not based on our good works?

The sermon highlights that being a good employee or employer does not contribute to our salvation. In Colossians 3:23-24, it points out that whatever we do should be done heartily as to the Lord, explaining that our ultimate reward comes from Him, not from our deeds. This emphasis on grace reflects the sovereign grace teaching that salvation is solely through Christ's work on the cross, and not dependent on our actions. The doctrine of substitutionary atonement is highlighted, where Christ fulfilled the law perfectly on our behalf, demonstrating that it is His righteousness that grants us salvation, not our own. Understanding this distinction encourages a heart of thankfulness and obedience as a response to His grace.
