7 But we have this treasure in jars of clay, to show that the surpassing power belongs to God and not to us. 8 We are afflicted in every way, but not crushed; perplexed, but not driven to despair; 9 persecuted, but not forsaken; struck down, but not destroyed. 10 We always carry around in our body the death of Jesus, so that the life of Jesus may also be revealed in our bodies.

The treasure is The Word, Christ, God. The clay pots are us as believers in Christ, who is the power of love, the anti-world. We ourselves are fragile, broken, flawed, yet He still stays in us. The world will try to kick the God out of us; family and friends will either embrace us or reject us, we will offend people, troubles will assail us, Satan will do everything he can to get us to capitulate. We are but simple jars of clay.  If we are filled with the Word, the love of Christ, that makes us strong. He will always be in us, giving us strength, endurance, and confidence no matter how violent the ride.
Remember, God could have had anyone give the message, but He has chosen the common people to spread the word. He has chosen simple people to start the revolution, to push back the darkness of the world, of Satan. He chose us so there would be no mistake where the power lies.
He will allow trouble in this life, great pain of all sorts, for that is the way of the world. We know what the next life is like though.
From His light good things happen. Be the light no matter what your condition. Shake off the troubles the world throws your way, put on the full armor of God and attack fearlessly when He sends you out. Do not rue the cost, remembering what He has borne for us, what He has done for us.
