Early in our ministry I traveled as an Evangelist for about 5 years, preaching in different churches throughout Oregon primarily on the subject of "Calling the Church to Prayer."
During one especially dry season in my spirit, my emotions were spent. Perhaps you too have experienced a season where what you "felt" (i.e. emotions) and what you "knew" (i.e. intellect) where separated by a very wide chasm. That is the place in which I found myself.
