There are forces of death and destruction that are ever wanting to pull us down from the higher to the lower.  These forces are bent on our destruction.  The forces of darkness never give up.  They want to use us for unholy purposes. They would like for us to speak and act thoughtlessly.   These may appear at the time to be innocent, but they never are, and never can be.  We must be watchful, ever on guard, lest we voice words or express actions from the kingdom of darkness.

Jesus turned and said to Peter, “Get behind me, Satan! You are a stumbling block to me; you do not have in mind the things of God, but the things of men.” Matthew 16:23 (NIV)
