​Let your light shine before men in such a way that they may see your good works, and glorify your Father who is in heaven.

Matthew 5:16 NASB
Jesus calls us to be the light in the dark places. To give hope to the hopeless. To be a blessing to others. Everyday you should encourage someone by your actions. Loving others by your deeds and words. That in itself brings light into the darkest heart. Don’t be afraid to be the light God called you to be because someone is depending on you to show them the way. 
God bless
