Joshua 24: 26-27 Amplified 26 And Joshua wrote these words in the Book of the Law of God; and he took a great stone and set it up there under an oak that was in [the court of] the sanctuary of the Lord. 27 And Joshua said to all the people, See, this stone shall be a witness against us, for it has heard all the words the Lord spoke to us; so it shall be a witness against you, lest [afterward] you lie (pretend) and deny your God.

So if I go through my house and call my walls salvation and my windows and doors a praise to God then they too can be a witness FOR me!! They can be a testimony of praise! As the watchers are writting my account they can see! I AM A PRAISE TO THE MOST HIGH GOD!!! I have a witness in the earth. Glory to GOD!
