If others speak untruths about you, there is an immediate desire to defend.  This is human nature.  You as spirit know Truth.  You know if you have done right or wrong.  If you have done nothing wrong and your words would not be heard, ask your Self if you might say nothing at all.  “Then it might look as if I’m admitting guilt,” you say.  And we say, there is only one judge:  you, just as it is in Heaven, which is right here, when you hold in awareness that all of this is simply a test for remembering you are Love.  Respond always with love and you will have nothing to defend.
