Five is the number of grace.
Let us never forget that even when sin increases, God's grace super-duper abounds (Romans 5:20)
Notice that in the beginning, it was dark and without form before God:
"And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters." (Genesis 1:2)
God created the heaven and the earth--then it was without form and void.
Let's never forget that there can be no darkness without God first having created or restored something,
God always comes first.
Light has already been there.
God the Father invited His Son to come: "Let there be light."
Notice that he did not "make" the light, nor did He create it.
The Light was always with the Father at the beginning of beginnings:
1In the beginning was the Word, and the Word was with God, and the Word was God. 2The same was in the beginning with God. 3All things were made by him; and without him was not any thing made that was made. 4In him was life; and the life was the light of men. 5And the light shineth in darkness; and the darkness comprehended it not.
And Jesus is the Light of the World (John 8:12)
He has overcome the darkness, just as He was before all things with His Father, and the darkness could not last.
Rest in Jesus, the Light of your world, and know that the darkness cannot overcome you!
