Summary: While we tend to focus on the purity of such things as food, water, and air, we would be wise to focus more intently on the purity of heart that Jesus speaks of here. A purity if not possessed will prevent us from seeing God both now and eternally.
Blessed are the pure in heart, for they will see God.
The ermine is a short-tailed weasel that has the unique feature of having its fur change to a snow-white color in the win¬ter. God created this animal with this feature to protect it from others. The ermine instinctively protects his white coat against anything that will soil it.
Fur hunters in northern Europe and Asia take advantage of this unusual trait of the ermine. They don’t set a snare to catch him; instead, they find his home, which is usually a cleft in a rock or a hol¬low in an old tree. They smear the entrance and interior with grime. Then the hunters set their dogs loose to find and chase the ermine. The frightened animal flees toward home but will not enter because of the filth. Rather than soil his white coat, he is trapped by the dogs and captured while preserving his purity. For the ermine, purity is more precious than life.
Looking at what we have thus far stud¬ied in the previous verses, one who is bankrupt in spirit, broken with grief, submissive to God’s leading, living with an insatiable desire for righteousness, sharing with others the mercy he has received, he now turns his attention to the most precious passion he can pursue and that is purity of heart. Without a passion for purity, one will never see God, be a part of His kingdom, enter His presence, or enjoy His forgiveness. It is hard to imagine that there is anything more important than purity.
That being said, I can’t imagine any Bible subject harder to get a full grasp on than purity. It encompasses everything revealed in Scripture and draws upon every biblical theme. Hundreds of verses point to the need for, the pursuit of, the blessings of having, and the consequences of a failure to obtain. While in our day much time and effort is focused on the purity of such things as food, water, and air, we would be wise to focus more intently on the purity of heart that Jesus speaks of here. When Solomon tells us, “Above all else, guard your heart, for it affects everything you do” (Proverbs 4:23), we would be wise to listen.
For God, man’s heart has always been the issue. While throughout the world the idea of the heart has always represented the inner person, the seat of motives and attitudes, biblically it represents more than that. Biblically, the heart includes the thinking process, specifically the will. Solomon pointed out that “as a man thinks in his heart, so is he” (Proverbs 23:7), and Jesus asked on one occasion, “Why are you thinking evil in your heart?” (Matthew 2:8). The emphasis is always on the heart because everything flows from the heart. It is the spiritual center of one’s being, the battlefield on which God and Satan wage war for our affections and allegiances. The outcome in this battle for the heart is critical, for God knows if He has your heart, He has all of you. If He doesn’t have your heart, He has none of you.
The word “pure” is the Greek word from which we get “catharsis,” which means the cleansing of the mind or emotions. Scholars suggest that this word has basi¬cally two meanings. The first has to do with pure motives. Like the chaff that is winnowed from the grain or the impuri¬ties that are removed from metals through the refining process, this word speaks of a heart whose motives are pure, whose loyalty is undivided, and one which is guided by God’s word in a specific direction. Secondly, it refers to the holy life that is the end result of those Godly motives. This purity of life is not restricted to moral or sexual purity, but rather it denotes one who loves God with all of his heart and whose single-minded loyalty to God has affected every single area of his life. Put together, these definitions of purity speak of a singular focus and undiluted fervor for God, an uncompromising passion that wills the love of God into one’s life and is clearly reflected in everything that one thinks, does, and says.
