The saying follows Jesus' first passion prediction and his call to costly discipleship. Present shame or rejection is contrasted with the future revelation of the Son of Man.
Angelic accompaniment and glory place the event within an eschatological heavenly setting.
Daniel 7 provides the central Son-of-Man background, while Old Testament manifestations of God frequently involve glory and heavenly attendants.
Jesus explicitly calls the glory 'his Father's glory,' preserving personal distinction rather than claiming the Father and Son are the same person.
Jesus warns that whoever is ashamed of him and his words will face the corresponding response of the Son of Man when he comes in glory.
Allegiance to Jesus in the present is thus directly related to one's standing at the eschatological coming.
The passage is strong cumulative evidence because Jesus occupies the central role in the future heavenly manifestation and comes with the holy angels.
The Father's glory can be understood as shared or bestowed, so the verse should be integrated with Mark's fuller Son-of-Man material rather than isolated as a direct ontological statement.
