How do we know God saves who He chooses?

The doctrine of election is a critical aspect of sovereign grace theology, affirming that God saves individuals according to His will and purpose, not based on their actions or decisions. Romans 9:16 states, 'It is not of him that willeth, nor of him that runneth, but of God that showeth mercy.' This underscores the understanding that salvation is entirely attributed to God's grace and not human effort. God, in His sovereignty, has reserved a remnant who genuinely worship Him and have not bowed to false religions that emphasize free will over divine grace.
