While this book is very accessible and readable, the ideas it covers are by no means simple. This book covers both practical and spiritual approaches to God in prayer that utilize silence and presence to begin a relationship in prayer with God as Person, helpful for the novice and experienced in prayer.
Anthony Bloom offers practical tools to encourage prayer, such as pairing action with particular prayers, allowing particular time to pray, saying particular words to pray (sometimes ones that are honest rather than pious, simple rather than lovely), etc. This book centers on the idea that God is a Person and must be engaged as a Person. Particularly helpful is the idea that God can feel absent when we speak because we have not ceased speaking, or we have not truly sought Him. God is not simply a Being waiting to hear our words and ready to listen whenever we may choose to speak, but beyond all else a Person with Whom an interpersonal relationship is possible. The rest of the book grows up from this assumption.
Throughout the book, he creates a narrative that can assist the one who is praying. First, one approach the door, knocks, waits, then addresses God. This kind of mental narrative of prayer is a helpful one, first for it's practical application. Sometimes we pray outside a closed door. Sometimes we try to rush in, not waiting for God to meet with us. Or we will simply list the our need before God, without ever speaking to Him. In all of these cases, the passing of time becomes the major problem. Silence itself may seem enjoyable to us, but silence must be accompanied by the passing of time around us without activity, and this can be an agony.
One chapter of this book, the chapter in which the book shines distinctly, addresses the matter of time:
"Now as far as time is concerned, there are moments when one can perceive that the present moment is there, the past is irremediably gone, it is irrelevant except to the extent to which it is still in the present--and the future is irrelevant because it may happen or it may not...What you have got to do is to be so completely in the present that all your energies and all your being are summed up in the word now. You discover with great interest that you are in the now."
This emphasis on the now- of all the past gathering behind and the future fractaling out ahead, both remaining entirely irrelevant to this moment of now- offers the opportunity to make the time spent in prayer potent and focused. Now is the moment we stand before the living God, and that "now" is moving along with us in time, not moving against us. There is peace in this thought, that for all of our hurrying and busyness and anxiety, time will carry us along from past to present to future all the same, but our true experience is only one of the present, and therefore we should be entirely present in it.
Silence, presence and a relationship with God as Person are unique features in an astoundingly short book.
