I don't think anon was suggesting that God is gone. Only that the satanists believe (or want their followers to believe) that God doesn't exist, only an "energy" which can be used to do what they wilt (completely amoral, without rules). Which leads to total selfishness, total evil, total nihilism.
But anons know that God does exist. A divine creator, father who created us with the power to create and to choose. To choose a path of good or evil. A loving father who is perhaps testing his children's capacity to "graduate" and become worthy of this divine power we are endowed with. And if unworthy (i.e., evil and destructive of His creation) then they must banished forever. How can they graduate with such a horrible disposition. They can repent at any time, and return to the love of the Father, but they choose not to. They deny his existence and abuse the God-given power of creation for nothing but their own gratification. There can be no universe ruled under such selfish dispositions —- only absence and destruction. The antithesis of God. There is no room for both of us in the universe. The reckoning is at hand.
