The Scriptures inform us of judgment to come.... So when can we expect His judgment to commence?
As shown in the Scriptures above, 1 Peter 4:17 shows there are two judgments to come. The first being the judgement on what is said to be the 'house of God' (the world). In that case, God uses the 8th king to carry it out. His rule comes upon the whole world and results in bringing about two groups. Those (weeds) that support the 8th king, thereby reject God/Jesus (apostasy) and those (fine seed/wheat) that reject the 8th king in support of God/Jesus. Those that reject the 8th king will have GT during that period. These are God's/Jesus' true people who will be enduring faithfully waiting for Jesus to come to deliver/recuse them from the 8th king's rule.
When Jesus does come after that appointed 42-month period of GT, then the 8th king and all that supported him will receive their judgment of death/killed off. All that rejected the 8th king will be the GC and those that rule with Jesus. (The sun, moon, star event occurs at the point between the 8th king's rule ending and Jesus coming. The two groups seeing that sign react in two ways based on who they supported during the 8th king rule.)
[17 For it is the appointed time for the judgment to start with the house of God. Now if it starts first with us, what will the outcome be for those who are not obedient to the good news of God?]
(During the appointed time is when they who are rejecting the 8th king will be suffering tribulation but then get relief. Then the outcome for those that support the 8th king will result in their destruction.)
[7 But you who suffer tribulation will be given relief along with us at the revelation of the Lord Jesus from heaven with his powerful angels 8 in a flaming fire, as he brings vengeance on those who do not know God and those who do not obey the good news about our Lord Jesus. 9 These very ones will undergo the judicial punishment of everlasting destruction from before the Lord and from the glory of his strength, 10 at the time when he comes to be glorified in connection with his holy ones and to be regarded in that day with wonder among all those who exercised faith, because the witness we gave met with faith among you.]

Yes, I believe the parousia will occur, hopefully soon, when Christ will judge the world and separate the wheat from the chaff.
The so-called 'parousia' is the same as Jesus' 'second coming' and does not take place until after the 8th king rule.
As already said above...the 8th king is the means by which the world is judged to start. The wheat and chaff are separated first by their own choice on who they choose to support, God/Jesus or the 8th king. Then when Jesus comes after the 8th king rule, he will do away with those that chose the 8th king as well as the 8th king himself.
