• Earthly Human [is current body that we have on Earth] {Flesh/Blood Body}
• Transitional Spiritual Human [non-eternal pre-glorified body – before Rapture while in Heaven]  {is Spirit Body – able to talk, think, etc – not like the Angels or Jesus yet}
• Post Spiritual Human [is eternal glorified body – at/after Rapture] {Spirit Body – actual eternal substance – similar to what Jesus has except we will not be God}

Reasoning:

So you don’t get confused if you watch the Discovery Channel or if you listen to experimental scientist who are now talking of Trans-Humans [machine/human mix] and Genetic-Altered Humans.

In current Heave saved will have Transitional Spirit Human bodies that have substance.} {Ecclesiastes 9:5 refers to second death in Lake of Fire where sinners will be no more ever again. Jesus said  that those in Heaven and Hell have substance and are alive [aware and function].  The reference to “not know” refers to — unsaved do not know because they have rejected God through Jesus and do not believe what God/Jesus says about anything and they do not care to know.]

— II Corinthians 5:6-8 states that upon death, saved will be with the Lord in Heaven, upon death our bodies go into the grave.  Saved receive their glorified immortal bodies later.

—- 1 Thessalonians 4:13-18 states that glorified bodies and immortality are obtained [for those dead & in Heaven and those alive and gathered at the rapture] at the time of the rapture with those dead & in Heaven receiving such first and then those alive & gathered thereafter………..It should be noted that at this time our Spirit is joined with our Spirit body for a glorified body and given immortality. How, only God knows.]

—- It should be noted that those saved dead in Tribulation and those who are saved in 1000 yr reign receive their glorified bodies at a separate time than those gathered in rapture.
