Tinka, that is a great question. The Bible says, "Let everything that has breath, praise the Lord". I talso says that if we dont' praise Him, the rocks will cry out. Now, we know that rocks don't have a mind, but this text seems to say that just because He is their Creator, inanimate things can praise God.
I have to believe that just because one's life or mind seems incapable, that God can still reach that person in some way. That is a beautiful thought!
