The Tribulation is God's judgement on the unrighteous- not on His children.
In every instance in Scripture in which God sent judgement, He first removed His people from the scene, i.e. Noah, Lot, etc.
Besides, Jesus said that the Rapture is the blessed hope and what hope is there if believers are to suffer the judgement intended for those who have chosen to reject God's Son!
