Use Your Walls
Now, actually it’s a puzzle. Because who needs walls when Hashem sees everything anyhow? I need my walls to testify on the Day of Judgment for or against me? I need my furniture to testify? Doesn’t Hakadosh Baruch Hu see and know everything Himself? Isn’t He a good enough Witness? It’s a good kasha.
And the answer is that it’s not for Hakadosh Baruch Hu these witnesses. He doesn’t need them. But we need them; because it’s difficult for us to live with things that we don’t see. We can talk about malachim and the Eyes of Hashem and we can believe it too, but it’s more effective when you know that the walls are watching. Hakadosh Baruch Hu is the real Witness, but if you know that the walls are going to testify, so for the sake of your walls you’ll behave.
And we shouldn’t belittle that! Don’t think you’re too smart for such things! Because it’s not so easy to feel that Hakadosh Baruch Hu is looking. And therefore the more you make use of those walls, the more effective it is. The more you put into it, the more you’ll get out of it.
