When Yeshua rose from the dead, He rose not as a spirit, but as a person with a physical body which could be seen.
After His resurrection, He presented Himself to His disciples saying, Behold my hands and my feet, that it is I myself: handle me, and see; for a spirit hath not flesh and bones, as ye see me have. Luke 24: 39.
His disciples watched Him ascend. That is, the disciples saw Jesus go away from them in His physical, touchable, seeable body.
John 14: 19 A little longer
and the world will behold me no more, but YOU will behold me, because I live and YOU will live.
1 Timothy 6:13 In the sight of God, who preserves all things alive, and of Christ Jesus, who as a witness made the fine public declaration before Pontius Pilate, I give you orders 14 that you observe the commandment in a spotless and irreprehensible way until the manifestation of our Lord Jesus Christ. 15 This [manifestation] the happy and only Potentate will show in its own appointed times, [he] the King of those who rule as kings and Lord of those who rule as lords, 16 the one alone having immortality,
who dwells in unapproachable light, whom not one of men has seen or can see. To him be honor and might everlasting. Amen
2 Peter 2:2 that YOU should remember the sayings previously spoken by the holy prophets and the commandment of the Lord and Savior through YOUR apostles. 3 For YOU know this first, that in the last days there will come ridiculers with their ridicule, proceeding according to their own desires 4 and saying:
Where is this promised presence of his? Why, from the day our forefathers fell asleep [in death], all things are continuing exactly as from creations beginning.
These one will not 'see' Jesus ( physically) that is why they asked this question. Because Jesus will arrive only in the heavens. These one do not 'see' the signs of his presence.
All these scriptures have to be in harmony to get the correct meaning.
Acts 1:9-11: While they [Jesus apostles] were looking on, he was lifted up and a cloud caught him up from their vision. And as they were gazing into the sky while he was on his way, also, look! two men in white garments stood alongside them, and they said: Men of Galilee, why do you stand looking into the sky? This Jesus who was received up from you into the sky will come
thus in the same manner as you have beheld him going into the sky. (Notice that this says
the same manner,
not the same body. What was the manner of his ascent? As verse 9 shows,
he disappeared from view, his departure being observed only by his disciples.
The world in general was not aware of what happened. The same would be true of Christs return.)
