12 Then Jesus again spoke to them, saying, “I am the Light of the world; the one who follows Me will not walk in the darkness, but will have the Light of life.” John 8:12
We must carry out the works of Him who sent Me as long as it is day; night is coming, when no one can work. John 9:4
For you were once darkness, but now you are light in the Lord; walk as children of light 9 (for the fruit of the light consists in all goodness, righteousness, and truth), Ephesians 5:8-9
If you know the light or have understanding of what God wants you to be or do, then do that.
