Light overcomes darkness. In nature, light displaces darkness. Turn on the light. Darkness is gone. Spiritually, Jesus brings light and displaces darkness.
“I am the light of the world. He who follows me will not walk in the darkness, but will have the light of life.” John 8:12
Jesus tells us we are the light of the world and calls us to let our light shine before men.
“Blessed are those who have been persecuted for righteousness’ sake, for theirs is the Kingdom of Heaven. “Blessed are you when people reproach you, persecute you, and say all kinds of evil against you falsely, for my sake. Rejoice, and be exceedingly glad, for great is your reward in heaven. For that is how they persecuted the prophets who were before you. “You are the salt of the earth, but if the salt has lost its flavor, with what will it be salted? It is then good for nothing, but to be cast out and trodden under the feet of men. You are the light of the world. A city located on a hill can’t be hidden. Neither do you light a lamp and put it under a measuring basket, but on a stand; and it shines to all who are in the house. Even so, let your light shine before men, that they may see your good works and glorify your Father who is in heaven. Matthew 5:10-16
