Let me try once more to explain parousia in simple language because some still do not understand what JWs teach.
Jesus becomes the newly established king of God's kingdom in 1914 as testified by the world events and the 7 times. He did come as king. Coming is a correct word to use when speaking of his arrival in 1914. But coming does not accurately depict the meaning of parousia because not only did he come but he stayed. He is now present. And he will continue to be present until his coming forth at Armaggedon. Then he will come forth to execute the judgements that have been rendered.
Revelation 6 explains it also. Verse 2 And I saw, and, look! a white horse; and the one seated upon it had a bow; and a crown was given him, and he went forth conquering and to complete his conquest. We know this is Jesus because Revelation 19 tells us outrightly that he is the rider of the white horse. He received the crown in 1914 and went forth conquering or subduing in the midst of his enemies as Psalms 110 tells us. As you read Psalms 110 notice the order of the action that Jesus takes.
2 The rod of your strength Jehovah will send out of Zion, [saying:]
“Go subduing in the midst of your enemies.”
3 Your people will offer themselves willingly on the day of your military force.
In the splendors of holiness, from the womb of the dawn,
You have your company of young men just like dewdrops...
5 Jehovah himself at your right hand
Will certainly break kings to pieces on the day of his anger.
6 He will execute judgment among the nations;
He will cause a fullness of dead bodies.
He will certainly break to pieces the head one over a populous land.
Did you notice what he does after becoming king upon Mt Zion? First he collects together his large army. These are the ones preaching the good news. Then he breaks kings to pieces. This is Armageddon.
The first part of his parousia involves gathering his organization. Some seem to think Jesus is not king and is not present because he has not crushed all the kingdoms of the earth. Big mistake to think that.
It is just as when a king returns after being absent to take up his rightful throne. Upon his arrival he realizes that many will not accept him as king. He knows beforehand that this will be the case. Although he has the power to overcome his enemies and take back his kingship immediately he does not do this because first he wants to find out who is loyal to him. He is present all the while as he gathers his loyal ones. After gathering the loyal ones it is time to destroy his enemies. At that point he comes forth and crushes all opposers. At no time after his arrival did he leave. He stayed and was present and conducted the work of gathering those loyal to him. Then at the appointed time he comes forth and destroys those enemies of his rulership. Really it is not a difficult thing to understand for those honest with themselves and look at the Bible without prejudice against JWs.
There are numerous scriptures that tells us that Jesus would become king after his ascension to heaven. Daniel 7:13,14, Daniel 2:44, Revelation 11 and 12, Luke 19 about securing kingly power, to name a few.
Yes, the truth is really simple. It is the apostates that want to mislead you and make it complicated.
