seems you would like it to be
of course not.
because as i said earlier, that would be a clear contradiction of scripture: death did not enter the world until sin.
therefore, Adam when created had in him no death - his natural body, of dust, was uncorrupt. he did not decay, because decay is cell death.
but when he sinned, then death entered in, and '
dying, he died'
therefore his natural body changed, so it is not correct to say the natural body does not change.
Paul also taught us, we shall be changed ((1Cor 15:51)) and that the natural body is sown in corruption and raised in incorruption ((1 Cor 15:42)) - physical Resurrection, after the pattern of Christ, Who physically rose from the dead and physically ascended.
Paul also taught us, speaking by the Spirit of God, that this is the very hope of the gospel, "
the redemption of our bodies" ((Romans 8:23)) - note that it is redemption, not destruction of our flesh we look forward to.
the dust, from which we are created in our natural form, was cursed, but Adam was not. and Christ, having made Himself for our sake a curse in order to redeem us, has taken away the curse.
the natural body very much indeed changes. Jesus never said it didn't.
in the first Adam it changed from incorruption to corruption, and in the Last Adam He will raise us from corruption to incorruption.
we will be changed, and we will not see decay or death any longer.
