I do not see any mention of the Bride of Christ, or His Bride in that passage. Can you give any scripture that references the Bride you mention here?
I Corinthians 15
50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
51 ¶ Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
53 For this corruptible must put on incorruption, and this mortal must put on immortality.
Paul, talking to the brethren, states there is an instantaneous raising of the dead. We are told of two resurrections in the Revelation, and this refers to the first resurrection. Notice it happens at the LAST TRUMP. If the events of the Tribulation Period, and Great Tribulation, happen after this (hence, pre-trib. rapture) how many trumpets are to be blown after the last trump?
.
Just want to say that there is always a trumpet sounding in reference to the Lord except on His birth.
In Psalms we read:
"God is gone up with a shout, the Lord with the sound of a trumpet." -Psa. 47:5 (KJV)
Now strangely enough, we don't see this happening in the passage referring to Jesus' ascent into heaven.
"And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight. And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel; Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven." -Acts 1:9-11 (KJV)
This is the only passage in the New Testament that records Jesus' ascent into heaven. That don't necessarily mean it didn't happen, just that it wasn't recorded.
In both passages of Paul's writings, 1 Cor. 15:51-54; 1 Thess. 4:13-18 we do have the sounding of the trumpet.
However, in 2 Cor. 1:7-8, Rev. 19:11-21; there are very different events described.
Then you have to factor in the seven trumpets of Revelation. (These are judgments though)
In order for scripture to harmonize, in order for scripture to not contradict itself, Acts 1:9-11; 1 Cor. 15:51-54; 1 Thess. 4:13-18 "harmonize."
2 Thes. 1:7-8; Rev. 19:11-21 do not.
Now, having said that, Acts 1:11 says: "this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven."
Show me, I challenge you, show me where Jesus ascended up into heaven:
"the Lord Jesus shall be revealed from heaven with his mighty angels, In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ:" -1 Thess. 1:7-8 (KJV)
Or, that Jesus ascended up into heaven:
"And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war." -Rev. 19:11 (KJV)
1 Cor. 15:51-54; 1 Thess. 4:13-18 must be a separate event than the ones recorded as shown.
God Bless
Till all are one.
