A thought ran quickly through my head, as often they do! Haven't I always said it's all about Jesus?
In this world we live in there is day and night. They were created. There is good and evil. Often day is linked to goodness where night is associated with evil. When we are able to see because of the light we are able to avoid evil, which must do its best (worst) work at night under cover of darkness.
While we are in this world we will always have good and evil. Some day the Light of the world will return and all evil will be removed and those who have found, received and followed the Light will reign with Him on earth before experiencing eternal life in Christ, in the Light.
So, we have a sun in the sky...the heavens, as it were...that brings the day. We also have the Son in the heavens who is also called the Light. It is His light which shines the truth upon us that prevents us from falling into evil. I'm convinced there was a reason for the two words, Sun and Son, sounding the same and both being in the heavens, and considered the light in/of the world.
Great words from Jesus Himself: ...“I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life." ...“he who walks in darkness does not know where he is going. While you have the light, believe in the light, that you may become sons of light.” (John 8:12,12:35-36) If you do not have Jesus you walk in darkness...
While you have the light... Reminds me of something else: Isaiah 55:6 - Seek the LORD while He may be found, call upon Him while He is near. And even better: I have not spoken in secret, in a dark place of the earth; I did not say to the seed of Jacob, ‘Seek Me in vain’; I, the LORD, speak righteousness, I declare things that are right. (Isaiah 45:19). Jesus has not hidden Himself from us. For 2,000 years people have been proclaiming the name of the Lord. People have declared those things that are right. He reveals Himself to those who choose to seek.
As I was reading in Revelation I was reminded of a scripture at the end that so fits with this. We are told when Jesus returns He brings a new earth with no more tears, death, sorrow, pain, crying, and a there will be a pure river of life, a tree of life, and no more condemnation (curse). (There is therefore now no condemnation to those who are in Christ Jesus, who do not walk according to the flesh, but according to the Spirit. - Romans 8:1) All things will be new, just like all things are new when we receive Christ as Lord and Savior. Today we have light and dark. We have lamps, fire, lanterns or flashlights, whatever it takes to bring light at night. But some day we will have no need for those things. All evil will be expunged. The Son alone will be our Light; an eternal light. We can walk in that light if we seriously seek Him.
Revelation 22:5 - There shall be no night there: They need no lamp nor light of the sun, for the Lord God gives them light. And they shall reign forever and ever.
