If you didn’t know any better, it might appear as though he was making a costly mistake. He would light a blazing fire, and let it burn until it was so intense that it made hell seem chilly. Next, when his crucible was hot enough, he would do something really bizarre: he would place silver or gold inside. The metals weren’t being burned for fun or fuel, however, but for refinement. In ancient days, craftsmen would do precisely this in order to purify gold and silver. By heating the metals until the dross ascended to the surface, and then scraping it away, the result was the finest gold and purest silver you had ever seen.
And this is what Jesus meant when He commanded believers to be “pure in heart” (Matt. 5:8a). A pure heart is one that is being continuously refined in the crucible of God’s saving and sanctifying grace, leaving behind a clean heart that is worth more than all of the gold and silver in the world. Jesus wants the hearts of His saints to be free from sin-impurities, contamination, and all other imperfections that do not belong. And purity is most vital in the heart, since the life we live flows from it (Matt. 15:19). If the spring of the heart is impure, then impurity will permeate one’s life through a stream of impure actions (Prov. 4:23).
Most importantly, only the pure in heart “shall see God” (Matt. 5:8b). As David explained, “Who shall ascend the hill of the LORD? And who shall stand in his holy place? He who has clean hands and a pure heart, who does not lift his soul to what is false and does not swear deceitfully. He will receive blessing from the LORD and righteousness from the God of his salvation” (Psalm 24:3-5). The writer of Hebrews likewise warned, “Strive for peace with everyone, and for the holiness without which no one will see the Lord” (Heb. 12:14). And this is one of the many reasons for Christ’s sacrificial death: “[Jesus] gave himself for us to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works” (Titus 2:14).
To have a pure heart, we must acknowledge the wickedness of our hearts (Prov. 20:9), and plead for God’s cleansing, as David did: “Create in me a clean heart, O God, and renew a right spirit within me” (Psalm 51:10). We must also immerse ourselves in the pure word of God (Psalm 12:6-7). The psalmist’s question and answer was spot-on: “How can a young man keep his way pure? By guarding it according to your word” (Psalm 119:9; cf. Prov. 19:8; John 15:3; 17:17).
