Proverbs 13:9 (ESV)

9 The light of the righteous rejoices, but the lamp of the wicked will be put out.

The wicked have a lamp which is the product of man’s labour and artistry, and which can produce light until its source of fuel is used up. Here is a reminder that for all of the so-called good works of the unsaved, their lives grow duller each day as they draw ever nearer to darkness, death, and hell. The righteous have light shining through them, which light has its infinite source in the Lord. Their lives grow brighter each day, until they shine perfectly in His glory and with His glory in them (Romans 8:18).
