Without even turning on the computer or opening a document, our computers and their wear and tear of use can help law enforcement know if we are right or left handed. They know which letters we use the most (like our passwords, encouragement to change your passwords often), and if we rest our wrists while typing or hold a proper form like taught in high school. I find this interesting.
Now think about yourself, sometimes people look at us and see the bags under our eyes, the extra pounds (or lack there of), or the sparkles (gray) in our hair. They can't determine details like a criminal investigator but they are able to see we aren't sleeping or eating well, and in addition to aging, we may be under stress. While there isn't one person who can look at our keyboards or our outward appearances and KNOW without a shadow of doubt what lies within, we DO HAVE a God who does. He created, designed, and loves us and knows EVERYTHING about us. Nothing is hidden.
Thank goodness. Not only does God know everything, He is right there along side you, 24/7/365. Don't try to carry the trouble or bury your troubles in the depths of a document or journal entry no one will ever read. Instead, fall to your knees and give it to Jesus. He's right here waiting for you.
