The image the sister posted is key. You can teach a subject for days. But illustration is a thousand words. Ones brain responds to visualization better than having to formulate an image in the mind of what someone is talking about.
If sis Ro had simply made a post talking about what the sister has on, 1) most would pass the post by, 2) many could not understand exactly what is being described and 3) it would be less effective.
We use every tool in our arsenal to reach and teach our people.
Imagery is everything. Did you not learn that in elementary school when doing class projects. "Illustrates on your class projects".
Thank you Mikyel Ibrahim, sir.
