On hearing of Peter's imprisonment, the church had gathered for a prayer meeting. Yet when God answers their prayers, they cannot believe it- Is this really a case of lack of faith or something else---It is fairer to them to suggest that they were limiting their prayers to requests which they thought was in accordance with what they knew about God. We do the same, and many of us will testify that God frequently exceeds our expectations.-These thoughts lead us naturally to consider two vital factors in prayer- knowing the will of God and having faith that he loves to answer and enjoys surprising us with his answers.
