What does the Bible say about the least of Christ's brethren?

In Matthew 25:31-46, Jesus explains that when He returns, He will separate people as a shepherd separates sheep from goats. The 'least of these' refers to His elect who are often marginalized and rejected by society. These individuals hold fast to the true gospel and are instrumental in God's plan for redemption. Caring for the least of His brethren is a true reflection of one's faith and commitment to Christ, signifying the acceptance and fellowship the elect have with each other as they serve the Lord.
