How do we know that Saul's encounter with the witch was not genuine?

The encounter between Saul and the Witch of Endor raises significant questions about the authenticity of the spirit that was summoned. The apparition claimed to be Samuel, yet it failed to provide Saul with any true hope or direction, remaining consistent only with deceit and despair. The Bible indicates that nothing can compel a soul in heaven to return, leading us to conclude that this spirit was an evil entity impersonating the prophet. Furthermore, had the true Samuel emerged, he would have directed Saul to repent and seek God's forgiveness. Instead, this false spirit only confirmed Saul's downfall and offered no real comfort, illustrating the futility of seeking solace in forbidden practices beneath God's truth.
