Imagine you have a big, strong, very sweet dog. If you take care of him, give him food and affection (love), what will he do? He'll always stay close to you and won't let any scary animal get near (protection).
The Bible says Wisdom (obeying God and your parents) is just like that strong friend. If you "abandon" her (by doing wrong, stubborn things), you end up alone and unprotected. But if you love doing what's right, Wisdom stays by your side like an invisible shield!
