One of the definitions of the word “filter” is: “any substance, such as cloth, paper, porous porcelain, or a layer of charcoal or sand, through which liquid or gas is passed to remove suspended impurities or to recover solids.”
In our human bodies, we have several filters; organs, whose main purpose is to filter out impurities in our blood. Here are some vital filters:
The Kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine.
Every day, the two kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid.
The kidneys are important because they keep the composition, or makeup, of the blood stable, which lets the body function.
Each kidney is made up of about a million filtering units called nephrons. The nephron includes a filter, called the glomerulus, and a tubule.
The nephrons work through a two-step process. The glomerulus lets fluid and waste products pass through it; however, it prevents blood cells and large molecules, mostly proteins, from passing. The filtered fluid then passes through the tubule, which sends needed minerals back to the bloodstream and removes wastes.
The Liver is a large, meaty organ that sits on the right side of the belly. Weighing about 3 pounds, the liver is reddish-brown in color and feels rubbery to the touch. Normally you can’t feel the liver, because it’s protected by the rib cage.
The liver’s main job is to filter the blood coming from the digestive tract, before passing it to the rest of the body. The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions.
The Spleen is an organ in the upper far left part of the abdomen, to the left of the stomach. The spleen varies in size and shape between people, but it’s commonly fist-shaped, purple, and about 4 inches long. Because the spleen is protected by the rib cage, you can’t easily feel it unless it’s abnormally enlarged.
The spleen plays multiple supporting roles in the body. It acts as a filter for blood as part of the immune system. Old red blood cells are recycled in the spleen, and platelets and white blood cells are stored there. The spleen also helps fight certain kinds of bacteria that cause pneumonia and meningitis.
When I read about these organs and their miraculous role in filtering our blood and keeping us in good health, I can truly say, along with the Psalmist, “I will praise You, for I am fearfully [and] wonderfully made; Marvelous are Your works, And [that] my soul knows very well.” Psalms 139:14 (NKJV)
Just as our bodies need filters to protect our blood, organs, and ultimately, our lives, so we need a spiritual filter to sift out the impurities from our souls; impurities that come from the world (1John 2:15), the devil (1 Peter 5:8), and yes, even our own selves. Jeremiah 17:9 (KJV) The heart [is] deceitful above all [things], and desperately wicked: who can know it. One of the most vital filters that God has provided to us is His word (The Holy Bible).
Consider the following scriptures:
Psalm 12:6 (KJV) 6 The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times.
Proverbs 30:5 (KJV)
Every word of God [is] pure: he [is] a shield unto them that put their trust in him.
The word pure in this verse is the Hebrew word Tsaraph, which means:
to smelt, refine, test
to smelt, refine
to test (and prove true)
smelter, refiner, goldsmith (participle)
(Niphal) to be refined
(Piel) to be a refiner
If we filter our choices through the word of God, we will prosper. The Lord has provided this navigation for us. “Thy word [is] a lamp unto my feet, and a light unto my path.” Psalm 119:105. If we do not filter our decisions through the Word of God, they will chip away at our Christianity. Decisions and choices which may seem trite and harmless can have devastating ramifications if they are not in alignment with God’s will. How imperative it is to guard our hearts and minds with the Word of God. It is the revealed will of God, and a proven tool for filtering out lies and exposing the truth.
Proverbs 4:23 says, ‘Keep your heart with all diligence, For out of it [spring] the issues of life.”
Ephesians 5:26-27 (KJV)
That he might sanctify and cleanse it with the washing of water by the word,
That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish.
