How do the teachings of John 8 reflect the concept of sovereign grace?

The episode of the woman caught in adultery encapsulates the essence of sovereign grace. Jesus intervenes personally, displaying His authority and mercy to forgive without the prerequisite of any works or law adherence on her part. This aligns with the historic understanding of sovereign grace, wherein God, in His mercy, chooses to save individuals based on His will and purpose rather than on human merit. Romans 9:16 declares, 'So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy.' This further underlines the notion that God's grace is entirely unmerited, freely given to those He has chosen to save.
