I used to sell diamonds, and when I brought a ring out of the showcase, I would put it on a black velvet cloth. The diamond ring sparkled and the prospective buyers admired it's beauty. I feel that is often how we are. We are that diamond, that beautiful gem that God wants to show off to the world.
Often very dark circumstances come into our lives, like that black velvet cloth, but God uses those circumstances to show us off. The world cannot handle life and it's problems without God's grace. We are to shine in this dark world.
Philippians 2:14 -15 says in the amplified bible " Do all things without grumbling and faultfinding and complaining and questioning and doubting. That you may show yourselves to be blameless and guiltless' innocent and uncontaminated children of God without blemish in the midst of a crooked and perverse generation among whom you are seen as bright lights in the dark world."
We are to radiate and magnify His presence in us in all situations, especially in the area of our mouths. Trials come to all of us , but I encourage you allow God's grace and His love flow out of you even in a hard time. The harder the time , the more He can shine through you.
