Satan
Why The loss Of Heavenly Prominence?

The folly in sin does introduce and influence the intended Eternal direction of 'Children of God' with additives that do produce negative results within the immediate environment of those 'Children of God' that do succumb to it!
So much so, that sin itself does always become massive and influential enough to aid for evil to grow and:
Deeply impact those 'Children of God' immediate environment with the evil of sin!
Gravely surround those 'Children of God' immediate environment with the evil of sin!
Gravely effect the intended Eternal direction of those 'Children of God' immediate environment with the evil of sin enough,…to bring forth destruction and death unto that originally intended Eternal direction!!!
Which since Satan did misuse his own Given Trust, intellect, and freedoms to initiate of the folly in sin amongst those 'Children of God' which Satan had been Given charge over, so too could Satan **No-More** be trusted by God with God's Own Heavenly Planned Workings concerning His Own 'Children of God'!
Thus Satan did Loose His Heavenly Prominence!!!
