What does the Bible say about many called, few chosen?

In Matthew 22:14, the phrase 'many are called, but few chosen' highlights the distinction between those who hear the gospel message and those who actually respond with faith. While many may hear the call of the gospel, not all are granted the understanding or inclination to accept it as the truth. This reflects the sovereign grace of God in election, where He chooses certain individuals for salvation according to His purpose, as seen in 2 Thessalonians 2:13, which speaks of God choosing believers for salvation through sanctification of the Spirit and belief in the truth.
