In what role does Jesus come for the church?

For the church, Jesus comes as the Savior and head of the body, not as King. At the second coming He comes to the Mount of Olives to Israel as King of kings and Lord of lords, but for His body, the church, He comes as Savior and head.

Les explains that our citizenship is in heaven, and from that same heaven we look for the Savior, not the King. He emphasizes that at the second coming Jesus will come to the Mount of Olives to the nation of Israel as King of kings and Lord of lords, but not for the church. For His body, the body of Christ, He comes as the Savior, as the head of the body, not the King. Les also teaches that Jesus will change our vile, corrupt body, a metamorphosis on a grander scale than a butterfly, fashioning it like His glorious body. Les suggests that to glimpse our new resurrected body, we should study the 40 days of Christ's resurrection, noting He looked normal, walked on two feet, walked with the disciples on the road to Emmaus, and then suddenly vanished.

Philippians 3:20

For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ:

Where does Jesus come at the second coming, and for whom?

At the second coming, He comes to the Mount of Olives, to the nation of Israel, as King of kings and Lord of lords—not for the church. He comes for His body, the body of Christ, as Savior and head of the body, not as King.
