How do we know salvation is not dependent on our own works?

In the sermon, it is made clear that salvation is not based on human merit or effort but is a work of God's grace. The Apostle Paul, in Romans 7:18, states, 'For I know that in me, that is, in my flesh, dwelleth no good thing.' This reinforces the belief that no confidence can be placed in our flesh because it is incapable of achieving goodness. Consequently, salvation is by grace alone, through faith in Christ, highlighting that it is God's purpose and power that saves us, not our own abilities.
