I think we all know what they MEANT TO SAY. Toilets have a function; a very useful function and without them we would all be still using outhouses. Perhaps they should have said something like: Please don't put anything unnatural in the toilet or Toilets are for human waste only. Still, none of these sound quite right. I am not really sure if there is a gentle way of conveying this message..??? Communication can be difficult at times, especially when the speaker and the hearer have different generic starting points...
WEB: John Chapter 8
 As he spoke these things, many believed in him.  Jesus therefore said to those Jews who had believed him, "“If you remain in my word, then you are truly my disciples.  You will know the truth, and the truth will make you free.”"
 They answered him, “We are Abraham’s seed, and have never been in bondage to anyone. How do you say, "‘You will be made free?’"”
 Jesus answered them, "“Most certainly I tell you, everyone who commits sin is the bondservant of sin.  A bondservant doesn’t live in the house forever. A son remains forever.  If therefore the Son makes you free, you will be free indeed.  I know that you are Abraham’s seed, yet you seek to kill me, because my word finds no place in you.  I say the things which I have seen with my Father; and you also do the things which you have seen with your father.”"
 They answered him, “Our father is Abraham.”
Jesus said to them, "“If you were Abraham’s children, you would do the works of Abraham.  But now you seek to kill me, a man who has told you the truth, which I heard from God. Abraham didn’t do this.  You do the works of your father.”"
They said to him, “We were not born of sexual immorality. We have one Father, God.”
 Therefore Jesus said to them, "“If God were your father, you would love me, for I came out and have come from God. For I haven’t come of myself, but he sent me.  Why don’t you understand my speech? Because you can’t hear my word.  You are of your father, the devil, and you want to do the desires of your father. He was a murderer from the beginning, and doesn’t stand in the truth, because there is no truth in him. When he speaks a lie, he speaks on his own; for he is a liar, and its father.  But because I tell the truth, you don’t believe me.  Which of you convicts me of sin? If I tell the truth, why do you not believe me?  He who is of God hears the words of God. For this cause you don’t hear, because you are not of God.”"
 Then the Jews answered him, “Don’t we say well that you are a Samaritan, and have a demon?”
 Jesus answered, "“I don’t have a demon, but I honor my Father, and you dishonor me.  But I don’t seek my own glory. There is one who seeks and judges.  Most certainly, I tell you, if a person keeps my word, he will never see death.”"
 Then the Jews said to him, “Now we know that you have a demon. Abraham died, and the prophets; and you say, "‘If a man keeps my word, he will never taste of death.’"  Are you greater than our father, Abraham, who died? The prophets died. Who do you make yourself out to be?”
 Jesus answered, "“If I glorify myself, my glory is nothing. It is my Father who glorifies me, of whom you say that he is our God.  You have not known him, but I know him. If I said, ‘I don’t know him,’ I would be like you, a liar. But I know him, and keep his word.  Your father Abraham rejoiced to see my day. He saw it, and was glad.”"
 The Jews therefore said to him, “You are not yet fifty years old, and have you seen Abraham?”
 Jesus said to them, "“Most certainly, I tell you, before Abraham came into existence, I AM.”"
 Therefore they took up stones to throw at him, but Jesus was hidden, and went out of the temple, having gone through their midst, and so passed by.
The Jews felt that THEY WERE GOD'S PEOPLE BY BIRTH; Jesus taught that God's people belonged to God on the basis of obedient faith. And so there was confusion and more confusion; that is... until the "I AM" statement. Then the Jews tried to kill Jesus. What kind of people do that anyway??? Perhaps its a middle eastern mindset or just characteristic of the Jews that made them act this way? No, the more I think about it, it seems its a general characteristic of all men, everywhere, to act like this. Which makes me wonder what sort of sign they would have instead of the one above. Maybe... Only put poop in the potty? No, that wouldn't work either... not literal enough!!!
