"DON'T FORGET WHO YOU ARE"!--(James 1:21-27)
Mirrors are like clocks, they are all around us!  I counted over 100 different places in my house where I could see my reflection or somewhat of an image of what I look like (windows, picture frames, mirrors, the fish pond, the pool, the silverware and plates, etc.  Many things offer you a reflection of yourself...some blurred and distorted, but you know that it is YOU nonetheless!)  
Without a mirror you would never know if anything was out of place!  You checked the mirror before you came to church!-(cow-licked hair, duck-breaded eyes)  A mirror cant do anything but hang there....you must respond to it!  
The mirror of the ancient Greeks and Romans was a disk of metal with a highly polished face, sometimes with a design on the back, and usually with a handle. Glass mirrors date from the Middle Ages. Mirrors play an important part in the modern astronomical telescope.  Magicians make things disappear through the illusion of mirrors.  In some carnivals they will distort mirrors to make you look fat, skinny, or wopp-sided!  A man who once had phantom pains was instantly healed of it by a trick of the mirror on his brain!  
Superstition claims that to break a mirror accidentally is considered bad luck because it is a sign that one has ceased to look "within".  Also another superstition is that witches have no reflection!  As one of the tools for "knowing" the self, mirrors are highly important.  In the disney classic Cinderella, The wicked queen asked a mirror regularly "Mirror mirror on the wall, who's the fairest of them all?"
IT DISPLAYS A REFLECTION---What would life be without seeing our REFLECTION?  Do you even realize how many times you look at yourself in a given day? (In the rear-view car mirror, in the bathroom each morning, in a store window, a makeup compact, or the visor mirror before you pull out of the driveway....or maybe the storm door of your house as you approach the front door to enter). 
(STORY)   "A drunk husband snuck up the stairs quietly. He looked in the bathroom mirror and bandaged the bumps and bruises he'd received in a fight earlier that night. He then proceeded to climb into bed, smiling at the thought that he'd pulled one over on his wife. When morning came, he opened his eyes and there stood his wife. "You were drunk last night weren't you!" "No, honey." "Well, if you weren't, then who put all the band-aids on the bathroom mirror?" (IT TELLS IT THE WAY IT IS!!!)
IT DISCLOSES A RESEMBLANCE---Actually we should all look alike...(In actions, attitudes, awareness) because the bible is our mirror; and if we are all looking at the SAME MIRROR we should all be making the same corrections!!!  All people are BEHOLDING something, and often it is not THE MIRROR they are making changes by....it's something else contrary to God's word!  (Like TV, the INTERNET, etc.)(You become what you look at!)(Lot pitched his tent towards Sodom!)  (Moses looked at God's Glory, and his FACE SHINED when he came off the mtn!)
IT DEMANDS A RESPONSE---When the Hebrews came into Egypt it took 400 years, but in time they looked at the wrong practices of the world, and soon forgot God's ways....so when God got them out of Egypt he gave them a mirror (The Law-10 commandments...are you breaking those?)
When building the Tabernacle in the wilderness, it is said in  (Exodus 38:8 -"And he made the laver of brass, and the foot of it of brass, of the lookingglasses of the women assembling, which assembled at the door of the tabernacle of the congregation. ")  It was almost like they were sending a messsage to heaven, "We are tired of looking at ourselves....it's time we look to God!"

(*We look into a mirror to:)
(1)-BEHOLD THE TRUTH-(it even reveals what you don't see-like a balding spot, etc.)  It's sort if like a person who swears "they don't look like a certain photo in real life"!  
*THE TRUTH IS:  (a)-HYPOCRITES are people who HEAR PREACHING every Sunday, but never DO a thing!  (b)-HELL is for those who "forget" (v.22).  (Psalms 9:17 The wicked shall be turned into hell, and all the nations that forget God. )  (c)-HAPPINESS comes from "good deeds" in the will of God (v.25b). (d)-HONEST and truthful christianity is in caring for the needy around you (v.27).  (e)-HATEFULNESS is found in the heart of a gossiper and slanderer (v.26).  THE MIRROR OF HIS WORD TELLS US THIS!!!
The MIRROR doesn't care who's looking into it....there are people here today that have enough money to buy a house with cash...but the MIRROR DOESN'T care...people who are ugly, beautiful, fat, skinny as a rail, educated and ignorant...but the mirror doen't care!  It will only and always tell the TRUTH about things!  Of all the powerful people who have served as kings and presidents; when they looked in the MIRROR, it didn't care how many millions of people voted on election day, nor what party they were afiliated with...it would simply say "I dont like what you are doing, you need to straighten up!
(2)-BEGIN OUR TOUCH-UPS!-(Parable of the 10 virgins/"Trimmed their lamps")
(3)-BOLDLY TRAVEL AWAY-(Nothing bothers the forgetful minded!)
*Sometimes there are things a mirror cannot do!  (Romans 8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:)---When I look in the mirror I see that there is no way I will ever be 18 again!  There are wrinkles that will never disappear...you see, the MIRROR can tell you what to do, but it can't do it for you!   If the mirror represents God's law, and I am told that some things the law cannot do....I'm glad there's nothing that Jesus cant do!!!!  THE MIRROR CANT CHANGE YOU...YOU CANT CHANGE YOU...BUT JESUS CAN!!!  (Like one man said who was addicted to chocolate cake...."I have an Iron will, and that cake has no power over me!  I can look at it all day, hold it in my hand, taste just the icing, have a small low-calorire slice, START MY DIET TOMORROW!"")
(Romans 5:8-10-" But God commendeth his love toward us, in that, while we were yet sinners (while we looked this way!), Christ died for us.  Much more then, being now justified by his blood, we shall be saved from wrath through him.  For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life.")
