This makes me think of God calling us to be separate from the world, giving us a purpose to serve (or rule with) Him in accordance to His plan in the hope of our names being written down in the book of life. When God speaks, His Word creates.
John 1:1-18 1 In the beginning was the Word, and the Word was with God, and the Word was God. 2 He was with God in the beginning. 3 Through Him all things were made; without him nothing was made that has been made. 4 In him was life, and that life was the light of all mankind. 5 The light shines in the darkness, and the darkness has not overcome it. 6 There was a man sent from God whose name was John. 7 He came as a witness to testify concerning that light, so that through Him all might believe. 8 He himself was not the light; he came only as a witness to the light. 9 The true light that gives light to everyone was coming into the world. 10 He was in the world, and though the world was made through him, the world did not recognize him.
