Why the Noahic Flood?

If you understood causation for the creation narrative and Elohim’s eschatological objectives through humanity concerning the Messiah and the defeat of Satan (Genesis 3:15; 1 John 3:8b), you would understand that the Adamic-Noahic generations had defiled themselves to such a degree; this, with the demonic, that they forfeited their fore-ordination as progenitors of the Messiah and the genome had become irreparably corrupted via the demonic; therefore, Elohim’s only viable option was to eradicate both generations save eight and begin anew with Noah and Noah’s family (Genesis 6:5).

This is why Elohim set apart, sanctified, Noah, Shem, Abraham, Isaac and Jacob (Israel) and ultimately Judah and why Elohim codified His spiritual law in stone at Sinai and presented same to Moses to disseminate among the Tribes as Elohim sanctified Israel’s children as His own and commanded that they be holy as He is Holy (Leviticus 21:8). Israel’s children were ordained to be the progenitors of the Messiah; the recipients of the New Covenant; the proselytizers of the Great Commission; a blessing to every family of the Earth (Genesis 12:3b); therefore, the sanctification or setting apart of Israel from the paganism that surrounded them was critically essential without compromise.

Elohim’s eschatological will concerning the restoration of holiness and righteousness to His Kingdom, a righteousness and holiness corrupted by a rebellious cherub angel before the creation of Time, will not be deterred by mankind’s free will choices via an Adamic sin-nature; therefore, Elohim has provided human kind with instructions, notifications, promises, concerning His eschatological plan for Time and  Eternity and Elohim has explained our temporary role in that divine  plan; this, via the Canon of Scripture and from the mouth of Elohim in flesh, Jesus our Messiah (John 1; Hebrews 1; Colossians 1; John 10:30;  John 14:9); therefore, human kind can freely choose to honor Elohim by faith in Jesus, trust Him and obey Him and LIVE – or – humanity can choose their own path through this temporary life constrained by Time and physics and die apart from Elohim’s will; that is, die the “second  death” in Hell as their unrepentant sin and absence of faith will NOT be permitted to enter the Kingdom, therefore, total destruction of the corrupted soul, mind, body, spirit, is tragically necessary as “nothing  impure” will ever enter the Kingdom of Elohim (Revelation 21:27).
