When a doctor wants to check the health of a patient, she will often check the eyes with a flashlight and the ears with an otoscope. Our eyes and ears are vital to our spiritual health too, for these are the key gateways through which thoughts come into our mind in the first place. What gets your mind ultimately gets you; what you allow in makes its way out into your words, actions and habits. This is why it's important you exercise control over your eyes and ears through the guarding of these gates and the feeding of your mind with a good, wholesome, godly diet. This sermon shows and inspires you how to do just that!
