“Could you please clarify how you arrived at the conclusion that the Church, the Body of Christ, is not of the number that return with Christ at His Second Coming?”
The saints who return with Christ at His Second Coming at the end of the Tribulation are returning for His earthly kingdom and the first resurrection. The prophetic saints are raised to “be priests of God and of Christ, and shall reign with Him a thousand years” (Rev. 20:6). Those who return with the Lord are the Bride of Christ, who have been “called unto the marriage supper of the Lamb” (19:9).
However, we are the Church, the Body of Christ (Eph. 1:22-23), not the Bride of Christ. We receive our resurrected, glorified bodies at the Rapture, seven years prior to the Second Coming. There is no need for us to return for a resurrection. At the Rapture, we are “caught up” (1 Thes. 4:17), and our bodies are raised and changed so that we might dwell in heaven forever. As we see from 2 Corinthians 5:1, “For we know that if our earthly house of this tabernacle were dissolved, we have a building of God, an house not made with hands, eternal in the heavens.” At the Second Coming, the kingdom saints return to the earth to have their bodies raised and changed so that they might dwell on the earth forever.
Those whom Christ brings with Him to the earth at the Second Coming are brought because the earth is their eternal home. However, for members of Christ’s Body, we will remain in heaven because heaven is our eternal home (Phil. 3:20; Col. 1:5) and the “one hope of [our] calling” (Eph. 4:4). In eternity, Christ will reign over those “both which are in heaven [Body of Christ], and which are on earth [Bride of Christ]” (Eph. 1:10).
