Since no one is "righteous" except those made righteous through Christ (2 Corinthians 5:21), and since only these have eternal life (Romans 6:23), we must conclude that these "sheep" (Matthew 25:32) either have been or perhaps, by God's election and foreknowledge, will be saved through faith in Christ. That faith has been evidenced by their response to the urgent needs of Christ's "brethren" (Matthew 25:40) during the tribulation period, a response surely endangering their own lives as well.
