"We will not always be safe from the adversary's influence, even within our own homes. We need to protect our nestings."  Boyd K Packer "These things I know" General Conference April 2013

We are never safe because Satan is always trying to tare us  down. We are not safe even in our homes. That is why we need to be on guard at all times. We need to be prepared to know what to do whenever anything arises. Just like Captain Moroni never rested and always prepared his weakest parts of his places, we need to make our weakest parts our strongest.
