I do and sometimes I read them.
Then, sometimes, I respond.
Sometimes I dispute, but the act of writing things down has always been helpful to me. It clarifies things. Scattered thoughts come together. Extraneous ideas are filtered.
It works for me.
There are many biblical examples of a person receiving an insight or even a revelation and writing it down. Sometimes, it is is even a command. One example, however, stands out.
Jesus was being manipulated ... or at least they tried ... by detractors and critics. They were trying to control His agenda in order to discredit Him. He took His time, made the dirt His paper and His finger a pen.
Then He wrote.
We don't know what. It is fun to speculate. Maybe folks could read His writing; maybe not. It possibly wasn't for them.
"They were using this question as a trap, in order to have a basis for accusing him. But Jesus bent down and started to write on the ground with his finger." - John 8:6
The fact is that when He was done, He knew what to say and what to do.
I can't think of a better endorsement for making notes to myself in all of history, literature, or scripture.
Make a note of that!
