In Judges 1:23 the ” house of Joseph” who were attacking Bethel sent men to spy it out. When the spies saw a man coming out of the city they asked him where the entrance to the city was ( verse 24).He showed them the entrance and with that knowledge they were able to strike the city ” with the edge of the sword”( verse 25).
When an enemy knows the entry point to a city, it’s able to conquer it.
Our enemy Satan is always trying to attack us to reach our entry point. He knows if he can get through our entrance, he has that much more leverage and is in a stronger position to do damage.
Our entry point is our heart. That’s why Proverbs 4:23 says:
Guard your heart above all else, for it determines the course of your life.
The enemy will try to get to our heart via our thoughts such as through thoughts of pride & arrogance, or via our eyes such as through looks of lust or envy, or via our emotions such as through feelings of fear. The enemy’s goal is always to reach, influence and involve our heart. He knows once he’s done that, he’s on the “inside of the city” where his potential to do damage is much greater. Where as Proverbs 4:23 says he can influence “the course of our life”.
Guard your heart, the entrance to your city. It determines the security of your whole life.
