Atheist asked: “Why did your God initiate a Flood that murdered men, women, babies?” “Your God is a tyrant.”

First of all, Elohim does not “murder” as He is sovereign over all life; Elohim possesses dominion over all life; Elohim is the Creator of all life, both angelic and human; humanity is created in the spiritual image of Elohim (Genesis 1:26-27) and receives the spark of life as life IS Elohim; therefore, when the body of flesh dies away that life, that spirit, encapsulated by decaying flesh simply returns home to the One who gave it as that human spirit is integral to all that Elohim is, Spirit (Genesis 1:26-27; John 4:24; Ecclesiastes 12:7; 2 Corinthians 5:8); therefore, Elohim does NOT murder Himself but receives back to Himself that which He gives exclusively for relationship and to further His eschatological purposes concerning the Realm of Time and the Spiritual Realm.

Second, our entire creation in Time, the Heavens, the Earth, the complex human genome, all matter, has manifest in response to an unfathomable coup d’état that manifest in Elohim’s Kingdom (the Spiritual Realm) mandating the extrication of those seeking to overthrow the dominion and sovereignty of Elohim (Luke 10:18; Revelation 12; Isaiah 14; Deuteronomy 28:11+; John 8:44); therefore, our Heavenly Father delegated all authority to His Son, Jesus Christ (John 3:35), as Author of the Creation Narrative (Genesis 1; John 1; Hebrews 1; Colossians 1).

It is the Son, Jesus Christ, who has methodically taken elements from the unseen Spiritual Realm and fashioned those elements into matter and placed that matter under the constraints of Time and physics (Hebrews 11:3) fitted appropriately for the Father’s eschatological purposes as the Son is also delegated the divine authority “to destroy the works of the Devil” (1 John 3:8b) using the Gospel of Grace as the “battle strategy” where Satan’s deception and evil is destroyed via selfless love and sacrifice, a sacrifice performed by Elohim Himself via the Son via the Holy Spirit at Golgotha (1 John 3:8b; Genesis 3:15-21); the Gospel of Jesus Christ having been ordained “before Time began” specifically to deal with Satan’s rebellion (2 Timothy 1:8-10).

Flood Causation,

It is unfortunate, tragic, but the Adamic and Noahic generations fell victim to unrestrained demonic influences (Genesis 6; Jude 1:6; Romans 1:18-32) and these generations of men, women and children were taken captive by the demonic and through deception, addiction to narcissism, immorality, the Adamic and Noahic generations morphed into haters of Elohim eschewing any semblance of sustainable mores, norms, values; therefore, Elohim was grieved that He had created human kind upon the Earth (Genesis 6) as Elohim refused to make any attempt to set-apart or sanctify a people group from the Adamic and Noahic generations through whom He would introduce His Messiah and ultimately His Gospel whereby Elohim would defeat, destroy, the evil of Satan while strategically maintaining volitional love with His cherished angelic creation that remained faithful to Him during the before mentioned coup d’état.

Therefore, Elohim reluctantly destroyed all but eight of the Adamic and Noahic generations by water and Noah found favor with Elohim (Genesis 6:8) and through Noah, Noah’s family, Elohim began anew and ultimately sanctified a people group for His eschatological purposes via the Patriarchy of Abraham, Isaac, Jacob (Israel); ultimately, through the Tribe of Judah, Elohim introduced His Messiah to the World and through the Gospel that is manifest via Messiah, Elohim fulfilled His promise to Abraham (Genesis 12:3b) and destroyed the works of the Devil (death, Hell, the grave) through selfless love historically chronicled via the divine words “It is finished” (John 19:30).

Conclusion,

The destruction of the Adamic and Noahic generations was absolutely essential if Elohim was to destroy the works of Satan and provide a path to eternal life via the forgiveness of sin via the Gospel via Messiah Jesus via Elohim’s own selfless love; this, while maintaining volitional love with His angelic creation and simultaneously establishing a bulwark against future rebellion in the Kingdom where nothing impure is permitted to exist (Revelation 21:27) yet free will remains extant by necessity.
