My wife bought some solar powered lights and put them along our sidewalk. They absorb energy from the sun during the day so they can shine at night.
We recently had a cloudy day, and my wife noticed that the lights didn’t shine that night. It appears that they need that regular exposure to sunlight before they can radiate any light of their own.
John 1:4 says this about Jesus—“In him was life, and that life was the light of all mankind.” Jesus says to his followers, “You are the light of the world…” (Matthew 5:14). It stands to reason that if we do not bask in the radiance of the Son, we will have no light to shine upon the world that so desperately needs it.
“In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.”—Matthew 5:16.
