Side line: FOREWORD p. 12 of "The Kingdom Interlinear Translation of the Greek Scriptures" (i.e. KIT) admits the term ' Jehovah ' is an inferior form of God's name, as does another WT Publication called "Let Your Name be Sanctified " (pp.16, 18).
Basically, God, whose name is Jehovah . . .
The EVENTS of the Book of Revelation did not start to take place until AFTER AD. 96 (approx.) So this alleged ' War in God's Heavenly domain (another impossibility (Psalm 5: 4) ASV) did not take place until AFTER AD 96 (approx.) so where did all your naughty spirit angels come from before AD 96?
Satan, the devil, the fallen angel and his army of demons (one third of the angels) Rev. 12:4
Also, when did your naughty angels become demons?
Yes indeed, and that would include not permitting thousands of naughty heavenly angels to exist for thousands of years with supernatural powers that apparently go around doing evil and attempting to corrupt mankind.
So, do you believe God is Just?
That God's justice is uniform and without variableness and the same Laws apply to all i.e. The wages of sin is death (Rom. 6:23) KJV. However ALL heavenly angels can never die (Luke 20:36) KJV and that means your alleged naughty ex-heavenly angels can never die and if that were the case then such a god is a god of injustice and self contradiction and certainly not the God of the Bible.
