Perhaps I should deliver some further definitions according to Erwin before we continue. I believe that feelings are the results of many things, but truth may or may not have anything to do with them. Truth, to me, is Jesus himself as the living Word and the Bible as the written Word. I would imagine that definition to be acceptable to most who read this. Facts are merely supposedly accurate bits of information about the world.
Feelings are our emotional responses to information, truth and experiences.
With those definitions, let us propose some situations. What if my friends are planning a surprise birthday party for me, and, as I notice what seems to be strange behavior, I become angry and think they are doing something bad. Regardless of my observations, the truth of the matter is different from the reactions of my emotions. Consequently, I must call my feelings liars. Suppose I feel that God doesn't love me or that he is getting even with me.
