What does the Bible say about the number of those who are saved?

The Scriptures clearly convey that salvation is limited to those whom God has chosen. Romans 9:6 states that not all who are descended from Israel are part of God's true people. This concept aligns with the doctrine of election, where God's sovereign choice determines who will come to faith. The distinctions made between the two groups—the elect and the non-elect—highlight God's mercy and righteousness. Examples throughout the Bible, including those found in the narratives of Moses and the Israelites, reinforce that only those designated by God will enter into His covenant promises, thus underscoring the significance of grace in salvation.
