If you were told that a program exists to invigorate your prayer life and it couldn't fail would you take it? I guess that most of us would say 'yes'! Prayer is vitally important to the life of the Christian and yet we struggle with it. We hear about different devices and schemes (8 ways to guarantee prayer success!) not recognising that God has already provided us with a prayer program in the Psalms. They show and share in our deepest feelings of anger, longing, fear, joy, despair, loneliness etc. and are all wrapped up in a package that addresses God directly from our hearts. T. M. Moore encourages us to develop the psalms as a guide to our prayers using different approaches to praying the psalms, which reinforces their diversity and power. This will provide us with reliable reference points, equip us with the right words to use when we need them, and give us assurance that the words we use will be pleasing to God. Moore highlights to us the importance of discipline in prayer and reveals insights into why the psalms have been a source of prayer and worship for God's people throughout the ages. When we look to God's word we will find it an immense source of satisfaction, sustenance and blessing in our own prayer life. God said it would be sufficient for us.
