Do you think it is remotely possible that my feeling of spiritual intensity, my feeling of closeness to Christ is equally strong every time I speak? Of course not.  There are times when I feel so overwhelmed by a sense of awe and adoration for Christ, that I can't wait to speak. There are other times I feel so far away from Christ; perhaps I am tired, sometimes I am just not in the mood, often I feel spiritually vacant and poverty stricken.  But it says on my calendar that I have to give a lecture or a sermon or a lesson. At such times, I am thinking, 'What am I doing standing up here trying to encourage other people when I am going through this?'  But I have found that the worse I feel, and the less I feel like it, the more I really feel dependent upon the power of God.
