But it is worth while taking time and trouble over the ordering of one's prayers. A man's intercessions, in particular, are not likely in practice to have the width, the range, and the variety which are desirable, unless they are planned and ordered in accordance with a coherent scheme which is thought out in advance. It is the part of wisdom to keep a note-book, in which names and subjects for intercessory prayer may be jotted down and distributed over the days of the week for use in due rotation. Such schemes, however, if drawn up and used, should be revised from time to time, and not suffered to become a mechanical burden or a legal bondage. There should be freedom and spontaneity in a Christian's prayers. It is well to have rules, and to try not to be prevented by mere slackness from keeping them. But it is important to see to it that the self-imposed rule is so framed as to prove genuinely conducive to reality in prayer, and suitably adapted to opportunity and circumstance: and it is very often a good thing from time to time, in the interests of freedom, quite deliberately to break one's rules. With regard to forms and methods of prayer, it is desirable that men should learn to pray freely in their own words, or even in no words at all. Provided a man remembers reverence, he need not stand on ceremony with GOD. But it is advisable also to use books and manuals of prayer --at any rate in the first instance: to use them, but not to be tied to them. Many such manuals have been compiled and published within recent years: the majority of them are unsatisfactory in varying degrees. A few, however, can confidently be recommended: especially _Prayers for the City of God_, compiled by G. C. Binyon (Longmans); _Prayers for Common Use_ (Universities Mission to Central Africa, Dartmouth St., Westminster); and _Sursum Corda, a Handbook of Intercession and Thanksgiving _, arranged by W. H. Frere and A. L. Illingworth (A. E. Mowbray and Co., Ltd.).
