The Enemy Within
The Great Wall of China is one of the wonders of the world. It is said to be the only man made structure on earth that can be seen from the moon. The cost and the effort that went into building it just boggles the mind.
When it was finished, the people relaxed. They knew they were safe. Nobody could possibly attack them now. It was impossible to either climb over or penetrate their superb protecting wall, behind which, they thought, they were safe.
But their enemies got through easily. How? They simply bribed one of the gatekeepers, who opened the gate and they came through unhindered.
The problem is there is something of an “enemy within,” a “collaborator” of the enemy, like the gate keeper in the story, in all of us, and Satan knows this only too well as he dangles the temptations before the windows of our souls.
If Satan’s wares were not attractive to something within us, they wouldn’t be much of a temptation! Worse still, many are not even aware of the existence of the “traitor” within.
