I appreciate reading John Woodhouse's blurbs at the beginning of the Moore College prayer diaries. Truth be known, I am more likely to read that bit that any other part. So I found an old envelope, opened it, and discovered these Woodhousian words:
It is important that those who pray believe in answered prayer (see Mark 11:24). This means to believe that God answers prayers. To pray, and yet not to expect God to answer, is hardly to pray at all.
