The second event was prophesied and we have been given significant details of how this will play out!
Luke recorded by The Holy Spirit in Acts chapter 1:
9 Now when Jesus had spoken these things, while they watched, He was taken up, and a cloud received Him out of their sight.
10 And while they looked steadfastly toward heaven as He went up, behold, two men stood by them in white apparel,
11 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.”
Jesus Himself told the Pharisees and His Disciples that He would return on the clouds of Heaven in Matthew 26:64. In both passages, Jesus was speaking to a Jewish audience for the church had yet to be formed. It is important to know who is being spoken to and differentiate between the Jews, the Gentiles, and the true Church.
Peter spoke (and Luke recorded) by The Holy Spirit in Acts chapter 3:
17 “Yet now, brethren, I know that you did it in ignorance, as did also your rulers. 18 But those things which God foretold by the mouth of all His prophets, that the Christ would suffer, He has thus fulfilled.
19 Repent therefore and be converted, that your sins may be blotted out, so that times of refreshing may come from the Presence of the Lord,
20 and that He may send Jesus Christ, Who was preached to you before,
21 whom Heaven must receive until the times of restoration of all things, which God has spoken by the mouth of all His Holy prophets since the world began.
Peter was urging the Jews to repent and be converted as part of the true Church who now have The Holy Spirit to rely on rather than the Pharisees. Only by accepting Jesus Christ as their Lord and Savior could their sins be blotted out and be refreshed in the Presence of THE LORD.
Paul emphasized this conversion as he wrote by The Holy Spirit in 1st Thessalonians chapter 3:
11Now may our God and Father Himself, and our Lord Jesus Christ, direct our way to you.
12 And may the Lord make you increase and abound in Love to one another and to all, just as we do to you,
13 so that He may establish your hearts blameless in Holiness before our God and Father at the coming of our Lord Jesus Christ with all His saints.
And in 2nd Thessalonians chapter 1:
6 since it is a righteous thing with God to repay with tribulation those who trouble you,
7 and to give you who are troubled rest with us when the Lord Jesus is revealed from Heaven with His mighty angels,
8 in flaming fire taking vengeance on those who do not know God, and on those who do not obey the Gospel of our Lord Jesus Christ.
9 These shall be punished with everlasting destruction from the Presence of the Lord and from the glory of His power,
10 when He comes, in that Day, to be glorified in His saints and to be admired among all those who believe, because our testimony among you was believed.
Make no mistake, there will be those who believe and are eager for His coming and there will be those who will suffer at His second coming.
Further, in 2nd Thessalonians chapter 2:
6 And now you know what is restraining, that he may be revealed in his own time. 7 For the mystery of lawlessness is already at work; only He who now restrains will do so until He is taken out of the way.
8 And then the lawless one will be revealed, whom the Lord will consume with the breath of His Mouth and destroy with the brightness of His coming.
9 The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders,
10 and with all unrighteous deception among those who perish, because they did not receive the Love of the Truth, that they might be saved.
11 And for this reason God will send them strong delusion, that they should believe the lie,
12 that they all may be condemned who did not believe the Truth but had pleasure in unrighteousness.
The Holy Spirit was given for the true Church to come forth and multiply on earth. Once the Church and The Holy Spirit are removed from the earth in the harpazo, the restraint is gone. This will allow the lawless one to be revealed and the tribulation will come forth. Now is the time to prioritize your works and focus on producing good fruit for the Kingdom.
