Jesus doesn't sneak back into the world. His return is an event marked by supreme authority and undeniable glory.
The disciples were asking Jesus about the end of the world, and they likely expected a subtle end or perhaps a triumphant earthly kingdom. But Jesus clarifies that His return will be a grand, public event. The phrase 'When the Son of Man comes in his glory' isn't just about appearance; it signifies His ultimate authority and reign.
He's not arriving in disguise or as a mere messenger. This arrival is the ultimate unveiling of His kingly status, complete with the royal entourage of all the angels. This isn't a quiet fading away, but a glorious inauguration of His final reign as King and Judge.
