An interesting parallel to the spiritual reality.
First that it is in Adam that all have died. Even Eve.
Second that the gift of the Holy Spirit fundamentally changes the nature of the one whom has received Him, that even though the old body of death may still linger and (while mortality lasts) compete to demand our fidelity it will still be removed, at either physical death or in translation for those still mortal when Christ returns, and with that everything competing with the new nature, that of the new birth, will be gone, just a memory.
Great point, we are truly a “new creation”...
To refine this idea further; Fellowship with the Lord in the matter of fruit-bearing results in the divine dispensing (into us) restoring us, supplying us enabling us to nurture spiritual offspring in life and growth. The more intimate we are with Christ, the more of Christ we assimilate and the more like Him we become, making us capable of producing spiritual offspring. Furthermore, when we have conceived and are bearing spiritual fruit, we share in the increase and growth of Christ in the new believer.
Everything positive in the universe is a shadow of Christ.
