While we all have the call to let our light shine so that God will be glorified, we need to ask a more specific and profound question:

"Lord, how do you want me to let my light shine? What are you specifically calling me to do to shine that light so others may know you better?"

But you are a chosen people, a royal priesthood, a holy nation, a people belonging to God, that you may declare the praises of him who called you out of darkness into his wonderful light. 1 Peter 2:9
