Well for one thing using your line of reasoning the prefect tense doesn't require that Jesus is currently in the same flesh he was resurrected in because it may imply the result of the coming was, and still is, ongoing. Secondly did you look at this ?
"
1Jo 4:2 Hereby know ye (εν τουτω γινωσκετε). Either present active indicative or imperative. The test of "the Spirit of God" (το πνευμα του θεου) here alone in this Epistle, save verse 13. With the clamour of voices then and now this is important. The test (εν τουτω, as in 3:19) follows.That Jesus Christ is come in the flesh (Ιησουν Χριστον εν σαρκ εληλυθοτα). The correct text (perfect active participle predicate accusative), not the infinitive (εληλυθενα, B Vg). The predicate participle (see
Joh 9:22 for predicate accusative with ομολογεω) describes Jesus as already come in the flesh (his actual humanity, not a phantom body as the Docetic Gnostics held). See this same idiom in
2Jo 1:7 with ερχομενον (coming). A like test is proposed by Paul for confessing the deity of Jesus Christ in
1Co 12:3 and for the Incarnation and Resurrection of Jesus in
Ro 10:6-10"
I don't understand what you're getting at. The force of the perfect tense is that the result of the event is present at the time of the speaker/writer. John said, whoever confesses that Jesus is come in the flesh. This indicates that the result of His coming in the flesh remains when John wrote. The use of the perfect tense would mean that Jesus came in the flesh and remained in the flesh at least until the time John wrote the epistle. I don't understand why you see this as potential rather than requited by the grammar.
I've read what you posted twice but don't see how is changes anything I've stated.
I parallel this with jesus condition before he came to Earth ( before the foundation of the world ). He didn't have a flesh Body then or do you suggest he did ?
No, I'm not suggesting He had a body before He was born. What I'm suggesting is that He "became" man and I've not seen anything in Scripture that would suggest that He became anything else after that. We're not told of any change that took place after He ascended or after John wrote the epistle. We also know that the angels at the tomb said He would return in the like manner as He ascended. I don't see anything that would suggest He is any different that when He ascended.
I can only say that heaven isn't on Earth because we're told the new Jerusalem comes to Earth out of heaven in Rev 21.
Rev 21:1-2 KJV And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. (2) And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.
Are you suggesting Heaven is inside our atmosphere and a flesh body can live there ? If this is the case do you suggest Jesus could be currently seen in our atmosphere if we are looking in the right place ?
Have you considered that Revelation is using figurative language? I would suggest that Jerusalem is not literally going to come out of the sky but rather the New Jerusalem is a reference to the restoration of the current Jerusalem.
18 But be glad and rejoice forever in what I create;
For behold, I create Jerusalem as a rejoicing, And her people a joy.
19 I will rejoice in Jerusalem, And joy in My people;
The voice of weeping shall no longer be heard in her, Nor the voice of crying.
20 "No more shall an infant from there live but a few days, Nor an old man who has not fulfilled his days; For the child shall die one hundred years old, But the sinner being one hundred years old shall be accursed.
21 They shall build houses and inhabit them; They shall plant vineyards and eat their fruit.
22 They shall not build and another inhabit; They shall not plant and another eat; For as the days of a tree, so shall be the days of My people, And My elect shall long enjoy the work of their hands.
23 They shall not labor in vain, Nor bring forth children for trouble; For they shall be the descendants of the blessed of the LORD, And their offspring with them.
24 "It shall come to pass That before they call, I will answer; And while they are still speaking, I will hear.
25 The wolf and the lamb shall feed together, The lion shall eat straw like the ox, And dust shall be the serpent's food. They shall not hurt nor destroy in all My holy mountain," Says the LORD. (Isa 65:18-25 NKJ)
God says "I create Jerusalem." That this is speaking of the present Jerusalem can be seen in the statement, "The voice of weeping shall no longer be heard in her." The vice of weeping is heard in the present Jerusalem. In that day Jerusalem will no longer suffer as it does today.
I 'm suggesting that we usually have concept of Heaven as being some place that is in space, however, I don't know that that is an accurate concept. Consider this passage about Elisha,
11 Therefore the heart of the king of Syria was sore troubled for this thing; and he called his servants, and said unto them, Will ye not shew me which of us is for the king of Israel?
12 And one of his servants said, None, my lord, O king: but Elisha, the prophet that is in Israel, telleth the king of Israel the words that thou speakest in thy bedchamber. {None: Heb. No}
13 And he said, Go and spy where he is, that I may send and fetch him. And it was told him, saying, Behold, he is in Dothan.
14 Therefore sent he thither horses, and chariots, and a great host: and they came by night, and compassed the city about. {great: Heb. heavy}
15 And when the servant of the man of God was risen early, and gone forth, behold, an host compassed the city both with horses and chariots. And his servant said unto him, Alas, my master! how shall we do? {the servant: or, the minister}
16 And he answered, Fear not: for
they that be with us are more than they that be with them.
17 And Elisha prayed, and said, LORD, I pray thee,
open his eyes, that he may see. And
the LORD opened the eyes of the young man; and he saw: and, behold, the mountain was full of horses and chariots of fire round about Elisha.
18 And when they came down to him, Elisha prayed unto the LORD, and said, Smite this people, I pray thee, with blindness. And he smote them with blindness according to the word of Elisha. (2Ki 6:11-18 KJV)
It's almost like there is another dimension that we cannot see unless God opens our eyes. I wonder if this is not where Heaven is at this present time. I wonder if this may be revaled in the kingdom, I don't really know but I don't think the New Jerusalem is literally going to come from space.
