The word 'light' here is 'owr' in Hebrew, which can mean 'illumination, bright, clear, morning sun, lightning, happiness, break of day, glory, shine, set on fire'. As you can see, this word 'owr' has a wide range of meaning in Hebrew.
Isaiah 60:2-3 then says, 'For behold, the darkness shall cover the earth, and deep darkness the people; but the Lord will arise over you, and His glory will be seen upon you. The Gentiles shall come to your light ('owr'), and kings to the brightness of your rising'.
People of God, even though the world may be getting 'darker and darker' (in every sense) in this end-time, 'but the Lord will arise over you'. The Word of God says so. The word 'arise' here is rather interesting. It is pronounced 'zarach' in Hebrew, which actually means 'to shoot forth beams of light, to appear on you like the sunrise'. Let me paraphrase the verse above now: Even though the world may be getting 'darker and darker', but as for you (the believers), the Lord will 'shoot forth beams of light' over you and 'appear on you like the sunrise'! Hallelujah! Take it, believe for it, and receive it. Amen!
Now, who is this 'light'? John 1:6-10 says, 'There was a man sent from God, whose name was John (the Baptist). This man came for a witness, to bear witness of the Light, that all through him might believe. He (John) was not that Light, but was sent to bear witness of that Light. That was the true Light, which gives light to every man coming into the world. He was in the world, and the world was made through Him, and the world did not know Him.
Notice the words 'true Light' here? Indeed, Jesus is the way, the truth, and the life (John 14:6), and this truth sets us free (John 8:32). And when this true Light comes, all darkness (even false lights) will have to flee. 1 John 2:8 says, 'Again, a new commandment I write to you, which thing is true in Him and in you, because the darkness is passing away, and the true Light is already shining'.
People of God, to be 'in this Light' is to be 'in Christ'! Jesus is your Light!
The word 'light' here in Greek is 'phos', which means 'to shine, to make manifest (to show up, to reveal)'. The Word of God says Jesus Christ is God manifested (showed up, revealed) and dwelt among us (John 1:14).
Just as Jesus Christ (the true Light) reveals God the Father, the light that shines (from the physical sun) also reveals the physical sun. In other words, without the light, you wouldn't know there's a sun!
Note: The Lord God Almighty forbid that we worship the physical sun, but He shows us the physical sun as a sure 'sign' that points us to Him and His only begotten Son, Jesus Christ (see John 1:1-18). If the 'physical sun' reflects God the Father, then the 'light' has got to reflect God the Son! The 'physical sun' and its 'light' cannot be separated. They are 'one'. If the 'light' is taken away from the 'physical sun', it is not called the 'sun' any more. May the eyes of our understanding be enlightened. Amen.
Isaiah 60:19-20 says, 'The (physical) sun shall no longer be your light by day, nor for brightness shall the moon give light to you; but the Lord will be to you an everlasting light, and your God your glory. Your sun shall no longer go down, nor shall your moon withdraw itself; for the Lord will be your everlasting light, and the days of your mourning shall be ended'.
Today, know that Jesus Christ is to you an 'everlasting light'!
So, friends, if you are currently going through a time of 'darkness' (in family, in relationship, in business, in career, in health, in finance, or in any other area of your life), and it seems your hope has also gone dimmer and dimmer, this is your time to receive the 'Light'. This 'Light' will also bring with Him a renewed hope for you. Amen. The Word of God says 'Christ in you, the hope of glory' (Colossians 1:27).
Know also that Jesus Christ Himself has already carried all your 'darkness' when He died for you on the cross, and in exchange, you can now receive the 'light'. The Word of God says, 'Now it was about the sixth hour, and there was darkness over all the earth until the ninth hour. Then the sun was darkened, and the veil of the temple was torn in two. And when Jesus had cried out with a loud voice, He said, "Father, into Your hands I commit My spirit." Having said this, He breathed His last. So when the centurion saw what had happened, he glorified God, saying, "Certainly this was a righteous Man!" (Luke 23:44-47)
And because He gave you this 'light', you can now therefore 'proclaim the praises of Him who called you out of darkness into His marvelous light; who once were not a people but are now the people of God, who had not obtained mercy but now have obtained mercy' (1 Peter 2:9-10). Have a year full of His light and the praises of the Lord. Amen!
