There is an ancient Greek legend of a warrior named Achilles. His mother had dipped him as an infant in the river Styx. That was supposed to make him invincible. But she held him by one heel which the protective waters didn’t cover. And it was through that heel that he received his fatal wound. From that story we get our concept of an Achilles’ heel, a weakness that really cannot be seen. To get to a mighty warrior, you have to find his Achilles’ Heel.

Each of us must ask, ‘What is my Achilles heel? We need to know our weaknesses, where we could easily be wounded spiritually. Then, as we rely on the Lord for his help, we will be protected from “the fiery darts of the wicked one” (Ephesians 6:16).
