Luke 9:26 KJV
For whosoever shall be ashamed of me and of my words, of him shall the Son of man be ashamed, when he shall come in his own glory, and in his Father's, and of the holy angels.
Jesus said that when He comes again He will do so with
His Own Glory
"...in the glory of his human nature, when his glorious body, as now, in heaven, shall be seen by all; and
in the glory of his office, as mediator, and the judge of all the earth; and
in the glory of his divine nature, which will appear in the resurrection of the dead, in the gathering of all nations before him, in separating one sort from another, and in passing and executing the definitive sentence on them.... "
The glory of His Father
As the express image of His Father, His own glory and that of His Father's are the same. Yet here we see it two fold, His own and His Father's together.
The glory of the holy angels
On top of this divine glory there will be added unto it the created glory that belongs to the angels as they attend to Him.
What a sight this will be when all of this glory explodes upon the face of mankind. Those who have come to know Christ and have been thereby humbled in this world will revel in the exaltation. But those who have been ashamed of Christ, who would not submit themselves to His kingdom and His sovereign rule upon them; Such glory as that day will reveal will cause them to cower in the shadows, seeking to hide from the light of this radiant glory.
