But if Jesus said wherever two or three would be gathered in his name there he would be among them.
Doesn't that show that he's been with his followers in spirit a lot longer than 1914 or any other man made date for his presence?
And since the word arrival when Jesus said he'd arrive "elth-" is the same for events in his parousia and second coming to judge the world why if he's been present already that he hasn't been judging putting sheep on the right and goats on the left.
The whole WT explanation of this is just too convoluted and roundabout to make any sense scripturally.
Any derivative and parallel explanation given by Second Adventist or Bible Student groups is likewise too filled with man made predictions and assumptions to be of any real value. They are just that, the thoughts of men.
Love the way Christ loved, and live the way he taught in the gospels, with caring for the downtrodden and the needy. This to me reflects his spirit, his presence in your life.
