I noticed the word (parousia) in the following..
Matt 24:23-27 NIV At that time if anyone says to you, ‘Look, here is the Messiah!’ or, ‘There he is!’ do not believe it. 24For false messiahs and false prophets will appear and perform great signs and wonders to deceive, if possible, even the elect. 25See, I have told you ahead of time. 26 “So if anyone tells you, ‘There he is, out in the wilderness,’ do not go out; or, ‘Here he is, in the inner rooms,’ do not believe it. 27For as lightning that comes from the east is visible even in the west, so will be the coming (parousia) of the Son of Man.
1 Cor 15:21-23 NIV / 1 Cor 15:51-52 NIV For since death came through a man, the resurrection of the dead comes also through a man. 22For as in Adam all die, so in Christ all will be made alive. 23But each in turn: Christ, the firstfruits; then, when he comes (parousia), those who belong to him.
1 Thess 4:15-17 NIV According to the Lord’s word, we tell you that we who are still alive, who are left until the coming (parousia) of the Lord, will certainly not precede those who have fallen asleep. 16For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first. 17After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever.
2 Thess 2:1-3 NIV Concerning the coming (parousia) of our Lord Jesus Christ and our being gathered to him, we ask you, brothers and sisters, 2not to become easily unsettled or alarmed by the teaching allegedly from us—whether by a prophecy or by word of mouth or by letter—asserting that the day of the Lord has already come. 3Don’t let anyone deceive you in any way, for that day will not come until the rebellion occurs and the man of lawlessness is revealed, the man doomed to destruction.
