“For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light,” Ephesians 5:8.
Light displaces darkness, but darkness cannot displace light as long as there is light. To test this truth, try this experiment tonight in your home. (It will also be fun to do with your children or grandchildren to teach this important biblical truth.) Plug in a nightlight in a room but do not turn it on. Then, turn off all the lights and allow the room to become completely dark. Allow time for your eyes to adjust to the darkness. Now, turn on the nightlight. Notice how lit up that tiny light can make the room. Light can over power the darkness of the room, but the darkness does not over power the light emitting from the tiny fifteen watt bulb.
The truth is this. God is the Creator of light (Gen. 1:3). In the Bible, light is symbolic of happiness, truth, knowledge and holiness. Believers are the children of the Light. Therefore, the Bible should be our guiding light for the way we should live presently in this dark world.
On the contrary, darkness represents sin. All humanity is in darkness until they come to the Light of the glorious gospel (2 Cor. 4:4). The Light of the gospel, Jesus Christ, illuminates the darkness of sin in one’s life. Without Him you are in a dark place. He is the Light of life!
Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life, (John 8:12).
