Let your light shine on social media.
First thought, Mt. 10:16: “Behold, I send you out as sheep in the midst of wolves. Therefore be wise as serpents and harmless as doves."
Several things to be aware of. "Social Media" platforms are commonly "free". They can afford to be because they collect every scrap of your personal information that they possibly can, and sell it to whoever will pay for it. So be conscious of what you are writing and what the consequences might be. This can be true of sites that have "Bible" in their names, by the way. I am not, however, saying "don't ever write if there might be negative consequences". But choose.
These platforms create silos through which your posts are directed toward others already of like mind. You can pour your heart out and not reach anyone new. But you might reach someone anyway, if God wills it.
The platforms are designed to be addictive. Going back to their beginnings, the basic model is that of a slot machine. Keep pulling that handle (scrolling) -- receive tokens ("likes") for your posting efforts -- pull it some more. "Gamification" is an important aspect of their design and evolution. Reflect on why you are doing what you are doing there. Glorify God; don't do it for your own glory.
Mt. 10:16 _literally_ applies to these sites. Believe it!
