It also depends on how one is defining the return of Jesus. During Jesus first coming, he was only performing miracles and proving he was the Messiah to a few people. To the rest of the entire earth, they didn’t even know about him. And yet there he was resurrecting the dead in a prototype kingdom of God n the midst of all his enemies and nonbelievers. And to the entire earth he was nonexistent until the preaching work published the news of his work and God’s “plan” of salvation by means of the ransom. The point us thst he was present and alongside his Apostles and God accomplished his purpose wirh the rest of the world unawares. He was in their midst.
As we @ JW see it, Jesus second time around began not with his human birth but with the birth of the Messianic kingdom in the heavens and the ousting of Satan. This is his second coming ( parousia or return) or rather, the beginning of his second coming because he takes action: first in heaven and finally when he is revealed to his enemies until the end of the 1000 year reign. In the meantime, since 1914 he has been alongside those in his congregation and the preaching work.
And look! I am with you all the days until the conclusion of the system of things…- 49That is how it will be in the conclusion of the system of things. The angels will go out and separate the wicked from among the righteous
