“We now have this light shining in our hearts, but we ourselves are like fragile clay jars containing this great treasure. This makes it clear that our great power is from God, not from ourselves” (2 Corinthians 4:7)

This “light” is the glory of the abiding Christ in us. As we walk by faith through this world our bodies become increasingly fragile, yet the glory revealed in us increases. We learn to preach Christ, and not ourselves. We learn to lean on Christ, not our own strength.
