What does it mean in 2 Corinthians 4:7 that we have treasure in jars of clay / earthen vessels?

TL;DR:

Second Corinthians 4:7 uses the metaphor of clay jars with treasure inside to depict our imperfect bodies into which God has placed a perfect treasure: knowledge of Himself. God’s power shines through us even in our weakness.

what does the bible say?

According to 2 Corinthians 4:7, we are like "jars of clay" or "earthen vessels" with a "treasure" inside. Though Paul is speaking metaphorically, Genesis explains that we are literally made from the earth (Genesis 2:7) for our Creator’s purpose (Isaiah 45:9; 64:8; Romans 9:21). God created light in Genesis 1:3, and He gives believers the internal light of the knowledge of Himself through His Son, Jesus Christ (John 8:12; 14:26; 1 John 1:5). The Bible teaches that this treasure leads to our imperishable inheritance of eternal life (1 Peter 1:3–9). In other words, our physical "jars of clay" will be resurrected one day to become glorified, eternal bodies (1 Corinthians 15:20–23). Throughout Scripture, God extends an invitation for whoever will (John 3:16; Revelation 22:17) to come to Him while we’re still in these physical bodies (1 Chronicles 28:9; James 4:8). Relying on the Lord for strength because of our inadequacy and in our hardships is a thread that runs through the Old and New Testaments (Jeremiah 17:5–8; Philippians 4:12–13). While we were dead in our sin and destined for destruction (Colossians 2:13), God made a way for us to be made new (2 Corinthians 5:17). Though our earthly lives are bound to end in physical death, in God there is fullness of life and hope for eternity (John 10:10; 1 Corinthians 15:50–58). This knowledge and resulting relationship with the Lord are the greatest treasures any earthly vessel can hold.

from the old testament

Genesis 1:3 records the creation of light: “And God said, ‘Let there be light,’ and there was light.” God gave outer light to the world and inner “light of the knowledge of the glory of God in the face of Jesus Christ” to us (2 Corinthians 4:6). Paul calls that inner light “this treasure” in 2 Corinthians 4:7.
In Psalm 8:3–5 David wrote, “When I look at your heavens, the work of your fingers, the moon and the stars, which you have set in place, what is man that you are mindful of him, and the son of man that you care for him? Yet you have made him a little lower than the heavenly beings and crowned him with glory and honor.” David recognizes the lowly nature of humanity and the majesty of God.
Moses wrote of the fleeting nature of human life in Psalm 90. He asked God to “teach us to number our days that we may get a heart of wisdom” (Psalm 90:12). He prayed, “Let your work be shown to your servants, and your glorious power to their children. Let the favor of the Lord our God be upon us, and establish the work of our hands upon us; yes, establish the work of our hands!” (Psalm 90:16–17). This is similar to Paul’s statement in 2 Corinthians 4:16–18. This life is temporary and fleeting, but we do not lose heart and instead recognize that God’s work is eternal.
In Isaiah 6:5, Isaiah sees a vision of God and declares, “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts!” God’s holiness was so magnificent that Isaiah became intensely aware of his own sin. Isaiah 6:5 presents a contrast between our inadequacy and God’s holiness.
Jeremiah 17:5–6 prophesied to the disobedient nation of Judah, warning of reliance on humankind rather than God: “Thus says the Lord: ‘Cursed is the man who trusts in man and makes flesh his strength, whose heart turns away from the Lord. He is like a shrub in the desert, and shall not see any good come. He shall dwell in the parched places of the wilderness, in an uninhabited salt land.” Judah relied on jars of clay rather than the Maker of all. In contrast, “Blessed is the man who trusts in the Lord, whose trust is the Lord. He is like a tree planted by water, that sends out its roots by the stream, and does not fear when heat comes, for its leaves remain green, and is not anxious in the year of drought, for it does not cease to bear fruit” (Jeremiah 17:7–8).

from the new testament

In 2 Corinthians 4:7, Paul writes “But we have this treasure in jars of clay, to show that the surpassing power belongs to God and not to us.” This verse metaphorically compares our physical bodies to "jars of clay" or "earthen vessels" with a "treasure" inside. We’re all different, each designed by the Heavenly Potter for His purposes (Isaiah 45:9; 64:8; Romans 9:21). Our bodies are temporary housing places for the treasure God has given us, namely, "the light of the gospel of the glory of Christ" (2 Corinthians 4:4).
God blesses us with the opportunity to be used toward His glory, as seen in 1 Corinthians 3:7: “So neither he who plants nor he who waters is anything, but only God who gives the growth.” We proclaim the gospel to others, but we do not do this of our own strength. We are merely the sowers, planting the seed God has given us; the growth is the Lord’s. The treasure in us is God-given.
Our strength lies in the Lord, as expressed in Philippians 4:13: “I can do all things through him who strengthens me.” Paul could endure persecution, prison, and beatings and still carry the gospel message and rejoice in God because of the strength God gave him (Philippians 4:4). In just our physicality—our jars of clay—we are hopeless. But with the Holy Spirit inside us, we can be used for God’s glory and furthering His kingdom.
After Paul mentions having “this treasure in jars of clay,” he goes on to describe persecutions and commitment to sharing the truth of the gospel with others. He then writes, “So we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day. For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison, as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal” (2 Corinthians 4:16–18). The treasure is in a temporary, earthly vessel. But the treasure is eternal. And, one day, our “jar of clay” will be resurrected to be with God for all eternity (1 Corinthians 15:50–58). With this eternal perspective, we press on in joining in God’s work in the world, knowing that He will bear the fruit (John 15:1–17).

implications for today

“Why me?” Have you ever asked that? It usually slips out when something bad happens, from serious tragedy to everyday annoyances. But we may also ask “Why me?” about God’s gift to us of the “light of the knowledge of the glory of God in the face of Jesus Christ” (2 Corinthians 4:6). Why do we deserve such a treasure? The answer is clear: We don’t. But God blessed us with it anyway because of His great love for us (Romans 5:8; 1 John 4:9–10). When we come to faith in Christ, we realize who we are and who God is. Like Isaiah after he saw a vision of God, our sin and God’s holiness become crystal clear (Isaiah 6:5). In Christ, God transforms us (2 Corinthians 5:7; Ephesians 1:3–14). As we offer ourselves to God, seeking Him and obeying Him, the indwelling Holy Spirit works in us to shape our beliefs, attitudes, and actions to be more in line with the truth of God (John 17:17; Romans 12:1–2; Philippians 1:6; 2:12–13; Galatians 3:1–9; 5:16–25). We will face hardships and persecutions—in putting our sinful nature to death, due to living in a fallen world, from spiritual warfare, and the like (John 16:33; 2 Timothy 3:12). But in all those struggles, when we abide in Christ, we can say with Paul “though our outer self is wasting away, our inner self is being renewed day by day” (2 Corinthians 4:16; cp. Isaiah 40:27–31). We can rest assured that the treasure we hold in these jars of clay is “a living hope” (1 Peter 1:3) and that we have “an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, who by God's power are being guarded through faith for a salvation ready to be revealed in the last time” (1 Peter 1:4–5). This knowledge of Christ and His light, and resulting relationship with the Lord, are the greatest treasures any earthly vessel can hold.
