Matthew 26:64 (KJV) Jesus saith unto him, Thou hast said: nevertheless I say unto you,
Hereafter shall ye see the Son of man sitting on the right hand of power, and coming in the clouds of heaven.
ἄρτι árti, ar'-tee
adverb from a derivative of
G142 (compare
G740) through the idea of suspension;
just now:—this day (hour), hence(-forth), here(-after), hither(-to), (even) now, (this) present.
ἀπό apó, apo'
a primary particle; "off," i.e. away (from something near), in various senses (of place, time, or relation; literal or figurative):—(× here-)after, ago, at,
because of, before, by (the space of), for(-th), from, in, (out) of, off, (up-)on(-ce), since, with.
Hereafter indicates that present time, as in just now, this day (hour). That means it goes against your understanding, because the Sanhedrin did not see Christ coming or sitting on the right hand of power at that very moment or even that day. For that matter no one has seen this event yet, and will not until Christ literally returns.
The only way the words of Christ make any sense is to understand what Christ was telling them
árti apó meant. Christ is saying,
Hereafter (because of this very moment in time) you shall see the Son of man....... Remember what that very moment meant was that Christ would be condemned to die!!! And it is because of His death, and resurrection that they and all humanity will see Christ coming in the clouds and sitting at the right hand of power.
