Why did Elohim create humanity knowing the propensity for compromise with sin via free will?

Because the creation narrative is infinitely more profound than most understand as the creation narrative concerns a response to an unfathomable coup/rebellion that manifest in the Kingdom of Elohim before Time was created and our temporary Earth, Time, the human genome created in response to that spiritual war between Elohim and Satan and this temporary Realm of Time is nothing more than a temporary repository or battle ground as Elohim removed the destruction of war from His Kingdom and placed that war here to deal with it apart from the Kingdom where nothing impure is permitted to exist (Rev 21:27).

Humanity is but a temporary player in this spiritual war between good v. evil through which the Gospel of Grace has been used to defeat Satan at Golgotha via the selfless love of Elohim in Messiah Jesus; in fact, the primary reason Messiah Jesus entered Time was “to destroy the works of the devil.” You and I possess the free will to choose an alliance with Elohim or Satan…our eternal destiny is contingent upon whom we ally with. I choose victory in Jesus (Revelation 5:5).
