The crucible is for refining silver and the smelter for gold,
but the one who purifies hearts ⌊by fire⌋ is the Lord. (Proverbs 17:3 GW)
(Context—Proverbs 17:1-6 GW)
No one can purify their own heart. No one. We can try but we’ll fail. We fail because we don’t have the right material to work from to develop a pure heart. We’re flawed.
Each of us is born with a selfish nature—a self-will.
This selfish nature isn’t obvious at first. When I first see and hold a newborn grandchild, well, it’s hard to imagine anything but purity in them. Each baby is wholly dependent on their parents, especially the nurturing care of their mother.
But over time—actually, not much time at all—this selfish nature becomes evident. It’s not just a child’s fascination with the word “no!” or their constant pushing of boundaries, it’s deeper than that. It’s embedded in each of us at birth—our individual self-will.
Our self-will is powerful, especially when it’s challenged and even when it appears to be subdued. No matter what the circumstances, it will eventually make its presence known. This can be a good thing many times but not when a pure heart is desired.
Many spiritually-minded people either claim or desire to have a pure heart. But this can only take place when the Creator of our hearts is allowed to work in us. Rather, when we allow the Lord to work our innate rebellion—aka, our selfish nature—out of us.
How does God purify a person’s heart? He uses external pressure. In this Bible version, the idea of fire or intense heat is expressed giving us a graphic illustration of God’s purifying process. But in most other Bible versions of this verse the word test is used to describe the process God uses to purify a heart.
It’s the tests of life that bring our selfish nature to the surface. Just as in purifying a precious metal like silver or gold in a furnace with intense heat that reduces the metal to a liquid, so God uses various tests in our life to reduce and refine us.
The intense heat of the refining process brings the impurities of the metal to the surface. These initial impurities are scraped off the surface. Then the process continues until the metal is pure enough to reflect an image on the surface like a mirror or still water.
Ever wonder why you undergo certain tests in life over and over? Tests related to hard-to-break habits, unhealthy relationships, or other internal struggles are intended to reduce us to a place of dependence upon God to overcome whatever the target is of this testing in our life.
God refines us so His image is reflected in us
As we experience these tests and allow them to melt us into a trusting submission to God, God will purify our hearts. Each test brings impurities to the surface. When the Lord scrapes these impurities out of us, He also heals the wounds they leave in us.
It’s not an easy process for most of us but it’s worth the work. The goal is to have a pure heart that we might see God (Matt 5:8). For now, we walk by faith—trusting in Him and His work in our hearts as He prepares us for the day we shall see Him face to face (1 Cor 13:12).
When you experience God’s testing in your life, allow it to melt your heart and submit to God with a full trust that He’s purifying your heart. As each test brings impurities to the surface, allow the Lord to scrape them out of you so He can heal and restore your heart.
Be willing to surrender your heart to the Lord as you come before Him in prayer, this will lead to a greater confidence in Him to answer your prayers, as you draw closer to Him through the purifying of your heart.
