This book teaches an old and secret way of prayer used in Christian monasteries and cloisters from the beginning. It is a way of prayerfully reading the Holy Bible in personal prayer, reaping the rewards of the word of God. This form of prayer is called Lectio Divina, divine reading. The method includes "worship in spirit and truth", which the Father seeks. It makes us grow toward becoming "spiritual people". It is the way the Lord set things up, as disclosed by St. Paul in his Letter to the Corinthians: "'What no eye has seen, nor ear heard, nor the heart of man conceived, what God has prepared for those who love him,' [...] Now we have received not the spirit of the world, but the Spirit which is from God, that we might understand the gifts bestowed on us by God. And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who possess the Spirit. The unspiritual man does not receive the gifts of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned. The spiritual man judges all things, but is himself to be judged by no one." 1 Cor 2:8-15 (RSV) 

Vatican II demonstrated how the Christian Church is very slow to develop and change. Lectio Divina was restricted to the clergy at first, not by design but because they were virtually the only ones who knew how to read. It is clearly taught in the Bible as what the Father seeks and is now slowly spreading throughout the world. The time has come.
