The brain originally is like an empty attic, and you have to stock it. (Arthur Conan Doyle, author of Sherlock Holmes mysteries)
When you buy a computer, it is already loaded with basic apps and software. But to make it capable of processing the work you intend for it, you will have to add other software and apps. At birth, certain abilities and capabilities are already “installed” in the baby. But for one to be a competent child, teen, and adult, a lot has to be “installed” through education and training.
Direct your children onto the right path, and when they are older, they will not leave it. (Proverbs 22:6)
