[rwa265]

When the Spirit enters your body your flesh comes to life. At the time of your death, the Spirit leaves your body. But if you are born again in the Spirit, your spirit remains alive with God.

[MHGinTN]

This is error. When The SOUL enters the body, you have life in the body. The spirit of everyone descended from Adam is dead even as the soul animates the creature body. Jesus has a way to animate His Resurrected body that did not require blood coursing through veins and arteries. Such a source of Life is deposited as only an earnest, into our human spirit when we are born from above.

The event depicted in 1 Thess 4:13-17 will change in a moment, in the twinkling of an eye, the creature body drawing life from the blood which carries the life, to drawing life directlty from the same means Jesus is utilizing today in Heaven.
