You are assuming Christ will only come once. Christ will come for His Church and appear only to them at the time of the rapture When brush returns at the end of the tribulation all eyes will see Him. Do you think the Church will mourn at the sight of their Lord as is depicted if the people’s response in this passage?
He does only return once, for the living and dead in Christ receive new resurrected bodies at Christ’s return. Why because he is headed to earth for the end of days, the binding of satan and the beginning of his millennia rule. No need of new bodies in heaven, they are for here on earth in the new Jerusalem. There is not two resurrections of the saints (pre trib and post trib) or two marriages of Him and His bride! One return, one resurrection after tribulation.
This 2 returns belief is not possible according to timeline of scripture.
He does appear only to his elect at his return... all the tribes of the earth will see him, Matt 24:30. Read what He has written not what false teachers have written. Satan would want the church not to be ready for the tribulation, thus this Jesus will whisk us away before the persecution of the church. God has never whisked the church away from persecution, we overcome persecution by the blood of the Lamb unto death gladly.
Matt 24: 30 Then will appear in heaven the sign of the Son of Man, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory.
