How do we know that few are saved according to the Bible?

The assertion that few are saved stems from Jesus' teachings in various places in Scripture, particularly Matthew 22:14, where He states, 'For many are called, but few are chosen.' This emphasizes the reality of God's sovereign grace in salvation, where it is not simply about the universal offer of the Gospel but the specific effectiveness of that offer in the chosen. In Luke 13:23-27, the Lord’s response to the question of whether few will be saved implies a sobering truth that many who think they are saved may be excluded. This aligns with the Reformed understanding of election and the necessity of responding to God's call with faith and repentance. Thus, the narrowness of the way to eternal life reveals that it is only through Christ that we are saved, and this truth underlines the importance of striving to enter through Him.
