The transfiguration of the Lord Jesus caused His body to shine and be glorified, revealing His Divine Nature to His closet disciples. the Lord revealed Himself to Peter, James, and John n His heavenly glory as the Son of God.

All the other disciples had only a limited vision of the Messiah in flesh and blood, and the multitude know Him only in His public life.

However, whose three men had the special right to see what no one else had seen. Is this not also the difference between those who are born of the Holy spirit and those who are only religious? Abandoning the sinful life and uniting with the Lord gives one the privilege of knowing Him.
