“You are light for the world.
A city cannot be hidden when it is located on a hill. No one lights a lamp and puts it under a basket.
Instead, everyone who lights a lamp puts it on a lamp stand. Then its light shines on everyone in the house.
In the same way let your light shine in front of people.
Then they will see the good that you do and praise your Father in heaven.
Matthew 5: 14-16 GW
Again, Jesus speaks of our identity, but in these verses He also addresses our position and purpose.
In addition to salt, we are light. We are to shine in darkness. When we "let" our lights shine, we are actually letting God shine through us. We should light the path to Jesus.
The words hidden and under a basket make me think of one who purposely holds back his or her talents or gifts. We hold back, making ourselves appear smaller as to not overshadow someone else or make them feel less than. There are other reasons...fear (don't want to fail), doubt (don't think you have what it takes for God to use you), ignorance (unaware of your gifts/talents and what to do with them) and false humility/pride (we hold back pretending to be humble but really just want someone to beg us). Whatever our reasoning, God's word clearly directs us not to hide. To do so is to disallow the Lord's positioning of us.
Then they will see the good that you do and praise your Father in heaven.
It all leads back to Christ!
God bless you.
