In all centuries past, there has been almost unanimous agreement among Bible believing commentators that “this generation” means the generation of Jews who lived between AD 30 and AD 70. We know that one man for sure got to see it. A man who did not die until after AD 98, almost 30 years after the destruction of Jerusalem and the Temple. A man who, as it happens, was referenced by Jesus when HE said to the Apostle Peter, “If I want him to remain until I come, what is that to you? You follow Me!” (John 21:22) That was the Apostle John. As it turns out, he did! Amen!
