You said...The Lord's coming against the Holy City ended the kingdom as it was manifested in the Old Covenant, and inaugurated the new kingdom of God.
What evidence can you provide that anyone saw the Son of Man coming in his kingdom in 70 AD? Matt 16:28
What evidence can you provide that the Son of Man has come with his angels in the glory of his Father, and that he has already repaid each person according to what he has done? Did Jesus only repay those alive in 70 AD and those who died before 70 AD? Does Jesus do this repaying each person every so many years or just in 70 AD and then again after everyone is born? Matt 16:27
You used Matt 16 as part of your assertion that Jesus already came (Preterist theology), then "you" should be able to give evidence these things already happened as prophesied in Matt 16. (What evidence do you have Jesus kingdom came in 70 AD? What evidence do you have that Jesus came with His angels in glory? What evidence can you provide that Jesus has already repaid everyone according to they have done?)
