I don't sense from reading what the Apostles wrote that they believed they were "in the ages to come" right now, when they wrote that. But, if what you say is true that should have included them.
Paul was still writing "for now we see through a glass, darkly/dimly; but then, face to face. Now I know in part; but then shall I know even as also I am known." (1 Cor 13:12) I wish we were in that time now!
Context, context, context. Always see the context.
"But God, who is rich in mercy, for his great love wherewith he loved
us, Even when we were dead in sins, hath quickened
us together with Christ, (
by grace ye are saved) And hath raised
us up together, and made
us sit together in heavenly places in Christ Jesus: That in the ages to come he might shew the exceeding riches of his grace in his kindness toward
us through Christ Jesus. For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast. For we are his workmanship,
created in Christ Jesus unto good works, which God hath before ordained that we should walk in them."
Us means The Apostles and everybody who were at that time and henceforth, '
quickened, together with Christ', and that quickening happened 'Even when we, [
they and us] were, [
are] dead in sins'.
The quickening is
retrospective looking
back to the cross, not an
expectation yet to be fulfilled in heaven. Why ever do you think The Gospel is such
Good News if you have to wait and "
wish we were in that time now!"?
Quickened is most definitely in the
past tense.
"
Created in Christ Jesus." Not by anything that we have said, thought or done. Only God is capable of creating. We are unable to create, even ourselves.
O come, let us worship and bow down:
let us kneel before the Lord our maker.
For he is our God;
and we are the people of his pasture, and the sheep of his hand.
To day if ye will hear his voice,
Harden not your heart, as in the provocation,
and as in the day of temptation in the wilderness:
Know ye that the Lord he is God:
it is he that hath made us, and not we ourselves;
we are his people, and the sheep of his pasture.
Enter into his gates with thanksgiving,
and into his courts with praise:
be thankful unto him, and bless his name.
For the Lord is good; his mercy is everlasting;
and his truth endureth
to all generations.
So Context, context, context, if you want to read truth in scripture.
