How can we be assured of our salvation according to the sermon?

The sermon emphasizes that our assurance of salvation stems not from our works or feelings but from God's unwavering faithfulness. Philippians 1:6 reminds us that He who began a good work in us will carry it on to completion. This assurance is rooted in the understanding that salvation is entirely of the Lord, as stated in Ephesians 2:8. Even when our faith feels weak, God remains faithful and upholds us, ensuring that all whom He has chosen will be preserved in Christ. This promise gives us peace and grounds our hope as we await Christ's return.
