1 Samuel 28:8 So Saul disguised himself, putting on other clothes, and at night he and two men went to the woman. "Consult a spirit for me," he said, "and bring up for me the one I name."
Have you ever heard the saying, "nothing good ever happens after midnight"? I suppose in the dark of the night, when very few others are around - people tend to do things they probably shouldn't do because they think no one is watching. . . Someone is always watching.
All the mediums and spiritists in the land would not welcome Saul into their home, because they knew he would punish them if he found out they were still practicing. Saul knew this and so he waited until evening - dressed up like someone other than himself - grabbed a couple of buddies - headed to Endor and asked the witch to do her 'magic'.
Something I tell my kids is that "if you can't do it in front of me or your dad, then you probably shouldn't be doing it". As adults, the question we should ask is "if you don't want God to see you doing it, then you shouldn't be doing it" - the hard truth is - God does see you doing it. No matter what it is - are you embarrassed? ashamed? It doesn't matter if no one else is around, or if you're behind a computer screen where no one knows your identity - God knows who you are and what you're doing. Don't let satan make you think that living outside the authority of God is ever an option.
