The Apostle Paul who knew that Christ lived in Him by the Spirit was never confused about the Physical return of Jesus Christ ..
In fact He warned other believers to not believe those who said that the Lord himself had already returned.
For if we believe that Jesus died and rose again, even so God will bring with Him those who have fallen asleep in Jesus.
For this we say to you by the word of the Lord, that we who are alive and remain until the coming of the Lord, will not precede those who have fallen asleep.
For the Lord Himself will descend from heaven with a shout, with the voice of the archangel and with the trumpet of God, and the dead in Christ will rise first.
Then we who are alive and remain will be caught up together with them in the clouds to meet the Lord in the air, and so we shall always be with the Lord.
Therefore comfort one another with these words. 1 Thess 4:13-18
The Gnostics would have you believe this is all spiritual nothing physical about it , but they are in grave error!!
They discount the Physical. They discount that the Word became flesh. They discount the Resurrection of Jesus and the Physical Return of the Lord ..
Many today even teach that the Lord has already came back in .. 70 AD huh 🤔 I guess missed the memo
My question is if Jesus has already come back then where is He ?? Because Hes physically coming back .
And why am I still in this body of corruption??
Because when He does come back corruption will be put off and incorruption will be put on in a moment in the twinkling of an eye
1 Corinthians 15:49,51-54 NKJV
And as we have borne the image of the man of dust, we shall also bear the image of the heavenly Man.
Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed-  in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed.  For this corruptible must put on incorruption, and this mortal must put on immortality.  So when this corruptible has put on incorruption, and this mortal has put on immortality, then shall be brought to pass the saying that is written: "Death is swallowed up in victory."
Look at what the men in white apparel told those who watched Jesus physically ascend into heaven
And while they looked steadfastly toward heaven as He went up, behold, two men stood by them in white apparel,
who also said, "Men of Galilee, why do you stand gazing up into heaven?
This same Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven." Acts 1:10-11
They said this same Jesus who was raised from the dead, and appeared to you for over 40 days in a flesh and bone body will come back in the same way that he went up.
Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ has already come.2 Thess 2:1-2
For we know that the whole creation groans and suffers the pains of childbirth together until now.
And not only this, but also we ourselves, having the first fruits of the Spirit, even we ourselves groan within ourselves, waiting eagerly for our adoption as sons, the redemption of our body.
For in hope we have been saved, but hope that is seen is not hope; for who hopes for what he already sees?
But if we hope for what we do not see, with perseverance we wait eagerly for it.
The last time I checked I still did not have a new physical glorified body .
2 Corinthians 5:2,5 NKJV
For in this we groan, earnestly desiring to be clothed with our habitation which is from heaven,
5 Now He who has prepared us for this very thing is God, who also has given us the Spirit as a guarantee.
We should never confuse the Holy Spirit living in us with the physical return of the Lord himself.. We shall see the King .
