We know so far that the judgment seat of Christ will occur prior to the wedding. As for the second advent, Christ will only descend from heaven and make war on Earth after his marriage (Rev. 19:11-16). Immediately after we are raptured, we theorize that the church will have time to enjoy our mansions before the judgment.
This is supported by what Christ had said: “And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also…” (John 14:1-3). This implies we would meet Christ immediately at our mansions after we are raptured. For how long we would enjoy them we do not know. After this, comes the judgment seat of Christ and following that the wedding.
It is accounted for by the relativity of time, which is also common scientific knowledge. It suggests that time passes at different rates to that experienced on Earth when deep in outer space. 2 Peter writes concerning time, “…that one day is with the Lord as a thousand years, and a thousand years as one day.” (2 Peter 3:8). 7 earth years would give God a large excess of time in heaven to do what is needed, including the judging of all Christians.
One group believes in a mid or post-tribulation rapture and denies a pre-tribulation rapture. Another believes that there will only be a pre-tribulation rapture. Both are wrong; there will be two raptures. They come to their conclusions from reading only a few verses and miss the whole picture. For the first rapture, the Church, who is Christ’s bride, must be brought up to heaven that they may proceed with their wedding. As for the second rapture, it will be for the saints to catch up to the wedding. It is written in Luke:
And ye yourselves like unto men that wait for their lord, when he will return from the wedding; that when he cometh and knocketh, they may open unto him immediately. Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them. (Luke 12:36-37)
Thus, a second rapture will occur for those tribulation saints who wait for the Lord. The first rapture of the church is also proven to exist as without it, there would be no wedding or associated feast for the tribulation saints to join.
Some use Matthew 25 to prove that a Christian can lose the Holy Spirit and miss the rapture. This is untrue because Matthew 25 applies to a different time period from that of the church. It is directed towards the tribulation saint, and tribulation saints have to work for their salvation, such as in the avoidance of the mark of the beast. These people must have had the faith and strict abidance to the commandments of the Lord Jesus. (Rev. 14:12) Christians however are saved by faith alone without works.
The church is the bride, and the book of Matthew reveals that the tribulation saints are the bridesmaids (Matt. 25:1-13). When Jesus said to those without oil in their lamps “I know you not” (Matt. 25:12), it indicated that these people were not saved (cf. Matt. 7:23).
Thus salvation as outlined in these verses is different from that of the church. There is a further distinction where the church of Ephesians 5 is referred to as a “virgin” (possibly 2 Cor. 11:2) while the tribulation saints/bridesmaids are “virgins” (Matt. 25).
Finally, it is written:
And he saith unto me, Write, Blessed are they which are called unto the marriage supper of the Lamb. And he saith unto me, These are the true sayings of God. (Rev. 19:9).
Those who are called to the supper are blessed, and that is why God tells these people to be watchful and wait.
