Parousia did not say the apostles were wrong in either of those posts. Parousia appears to be stating the futurist argument requires the apostles teachings of near, soon, at hand to be wrong. two entirely different things.
Paul clearly states the fulfillment of the ages had come up on the 1st century generation
1 corinthians 10:11 Now these things happened to them as examples and were written down as warnings for us, on whom the fulfillment of the ages has come.
Peter clearly states the end of all things was at hand in the 1st century, and that they were living in the last days
1 peter 4:7 The end of all things is at hand. Therefore be clear-minded and sober, so that you can pray.
acts 2:16-17
No, this is what was spoken by the prophet Joel:‘In the last days, God says, I will pour out My Spirit on all people.
John clearly states they were living in the last hour in the 1st century
1 John 2:18 Children, it is the last hour; and just as you have heard that the antichrist is coming, so now many antichrists have appeared. This is how we know it is the last hour.
James clearly states the coming of the Lord was at hand in the first century.
James 5:8-9 You, too, be patient and strengthen your hearts, because the Lord’s coming is near. Do not complain about one another, brothers, so that you will not be judged. Look, the Judge is standing at the door!
(just a little heads up, Keras, in other threads, has stated the apostles were wrong in regards to their time statements).
In regards to these statements, futurists are required to either state the apostles were wrong, or that "at hand", "near", or "soon", do not actually mean 'at hand', 'near', or 'soon, but must spiritualize them into "from God's persepective", even though God can, and has before, explained when things are far off (daniel 8:26) versus near (revelation 22:10).
