Faith is not imagination. Faith is based on tangible realities, albeit spiritual in its origin and form. It transcends hope and imagination. Faith is based on the certainty that a thing exists. For the New Testament believer, faith should be an unfettered belief in the existence of tangible realities.
"Faith Is Not Imagination" seeks to highlight the reality of faith. It also seeks to buttress the point that "certainty" and not "hope" should be the 'center piece' in the Christian walk.
Hope is key in the Christian experience. However the exercise of faith goes beyond hoping for something to happen. It amounts to walking in the certainty that something has already happened.
