These people believe that their behavior, sparked by fear and masked by their false personality or ego, will keep them safe. It doesn't. It simply makes them weak and weakens or eats away at any organization within which they are operating.
The people who sit idly by and allow these power-mongers to continue also contribute to the disintegration or the crumbling of the organization.
It takes strength, commitment, and clarity of purpose to put aside your fear of those who want to divide and conquer. Strength to know that God is on your side when you are trying to build a sacred space. Commitment to fend off the barbs and arrows of those who have only their own needs at the fore, and clarity of purpose so that you may "keep thine eye single."
Let your light shine on the darkness. Never let the hard-hitting tactics of those who seek only discord push you into the shadows. No matter how small your light is, it is greater than all the darkness combined.
