Most humans out of fellowship with God aren’t seeking Satan, but are instead merely seeking something other than God as a counterfeit to what He has already provided.
And in that counterfit, is Satan. Who best earns from lack of God? Satan of course!
Any soul not to God is to Satan, thus my stand and my statements.
It is also the conclussion of your own observation, despite your deliberations.
My point is that Satan is merely a powerful creature, not a parallel god coequal with God. We all have natural enmity to him, and it is an easy mistake to associate anything other than God as belonging to the Adversary, but that isn’t the case.
This doesn’t mean he doesn’t possess many, nor that he isn’t involved in much sin, but one of his goals to be make himself like the most high. The Adversary loves to be thought of in such high regard.
Now where the dichotomy is better revealed is in regards to the issues of good and evil.
Unlike sin which was settled on the Cross by our Lord and Savior, and by the Father judging all sin, past present and future, the issues of good and evil have not been so resolved.
Our human good today is parlayed into evil by the Adversary. Only Divine good has eternal merit. In a moment’s notice, our sin may be forgiven by 1st John 1:9. That is not the case with good and evil. They are resolved in time.
When we believe in God through faith in Christ, we are today sealed by the Holy Spirit along with a regeneration of our human spirit in salvation. There still remains post-salvation sin. It will separate our thinking from Him, but not our seal. Our soul is not relinguished to the Adversary when we sin, but we no longer abide by His Will when we turn away from Him.
BTW, regarding sin,...Satan hates sin. His counterfeit plan to God’s is filled with worldly order. One thing Satan can’t control is the ability of man to sin, regardless of what Satan commands.
