The idea that ‘Prayer is a key’ to revival does not tell us how to pray or the important basic things that we must grasp in order to live a transforming and influential prayer life. On the other hand, the keys of prayer lead us to the practical things that help us to pray, and what we must do to teach or to learn about prayer. This is a teaching on the keys of prayer with living examples of how prayer is a key. This method makes teaching or learning about prayer more powerful and practical.
‘Prayer is a Key’ gives enthusiasm and encouragement but it does not give a foundation on which to build a life of prayer, and enthusiasm that does not find a foundation does not last long. In order to continue, it needs enthusiasm to be continually aroused, but the foundation, which is learning about the keys of prayer, even if enthusiasm is not aroused, produces the fruit of enthusiasm and encouragement.
