2 Corinthians 4

Since God's light is the brightest, no one should brag about how greatly they perform. The glory belongs to God, Who uses we lumps of clay to demonstrate the magnificent brightness of His glory. Because we are His creatures and under His control, nothing need upset or dismay us. Not even the difficulties of life will dishearten us, for the things that are not seen far outweigh those temporary setbacks of what we can observe.
