How do we know that God's grace makes a difference?

The difference that God's grace makes is fundamental to understanding salvation in the Christian faith. As stated in the sermon, it is God who makes the distinction; it is not through our wills or efforts, but through His sovereign grace alone. This is articulated in Romans 9:16, emphasizing that 'it is not of him that willeth, nor of him that runneth, but of God that showeth mercy.' This truth highlights that belief and salvation are a result of God's initiative and choosing, assuring the believer of their secure position in Christ as part of the remnant He has preserved.
