In the past couple of weeks God has been revealing to me the names of sexual demons: Incubi and Sucubi. In this story of Tamar and Amnon was Amnon possessed by either one of these demons. Or, was Amnon the demon himself?
"I marvel that you are turning away so soon from Him who called you in the grace of Christ, to a different gospel, which is not another; but there are some who trouble you and want to pervert the gospel of Christ. But even if we, or an angel from heaven, preach any other gospel to you than what we have preached to you, let him be accursed. As we have said before, so now I say again, if anyone preaches any other gospel to you than what you have received, let him be accursed" (Galatians 1:6-9).
God said through Jude, "Beloved, while I was very diligent to write to you concerning our common salvation, I found it necessary to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints" (Jude 3). Yet you are claiming to have additional revelations that God hasn't mentioned before. By your own words you have labeled yourself to be a liar. "Indeed, let God be true but every man a liar" (Romans 3:4).
The names "Incubi and Sucubi" do not appear in the Bible. In the story of Amnon and Tamar (I Samuel 13) that Amnon was a son of David and half-brother to Tamar (I Samuel 13:1). Throughout the story, the blame for the rape is laid on Amnon's shoulders because it was his choice.
Quit seeking to excuse your own sins by trying to blame your poor choices on nonexistent causes.
