The scripture showing that all men die, is the same terminology used in Genesis when G-d told Adam and Eve...if they at this fruit they would surely die. G-d created man initially to live forever. This was a spiritual as well as a physical death, but it was not an instant death as we equate death. It meant basically that we were no longer eternal beings due to sin.
 
The fact is, the scripture saying the dead know nothing is a Jewish belief in Sheol...the grave. The soul that sins is made dead, we...the out called Ecclesia are not under that. That particular verse has nothing to do with the Rapture and the translation of flesh. Jeshua HAD to die in order to defeat death for us. So the word translated, is similar to transformed and transfigured. It is a process in which something already dead is made alive. In truth we who live away from G-d are dead. In both spirit and flesh.
 
In Adam all certainly die, as from Adam we are born into sin. That again is a simple statement that says just what it means. When we accept Jeshua, we are reborn, hence we were born, we died in sin, and now have eternal life. So we have already passed from death unto life. However, we will not die right before our flesh is transformed, for those of us who are alive and remain. We will simply be translated as Paul said.
 
However, some of those passages you quote have nothing to do with this particular subject, they simply mention death through sin, and bolster the Jewish belief of death and the grave. Nothing to do with the translation of flesh at the time of Rapture for those of us who remain.
 
Shalom.   Pete
