§ 2. _Prayer should be comprehensive yet definite._ In the Lord's Prayer each petition gathers into its grasp whole groups of desires, and all the petitions taken together give shelter under their hospitable shadow to every need and every aspiration that belong to human life. Great gifts are asked for--"Thy Kingdom come, Thy will be done on earth, as it is in heaven." In such requests we even claim things _for_ God as well as _from_ Him. The dignity of each several petition is marked. We are taught to expect royal gifts from our royal Father, gifts worthy of members of that royal family, the children of the Incarnation. The effect of the persistent use of these comprehensive petitions has filtered right through human experience and taught man to expect great things in all departments of life, in science, in invention, in literature. Man's best desires have become a true measure of his possibilities.
The prayer that is shaped after the great model must not be timid or faltering, but bold and aspiring. It is a great mistake for one to be satisfied with praying for, say, purity instead of "Thy will be done on earth as it is in heaven." That is to ask for the crumb from the rich man's table when the rich man is beseeching you to sit by his side and share all that he has. Let us pray for purity by all means, though not as if it were a flower that grew in a bed all by itself. We can get one Christian grace only by aiming at all.
No less marked than the comprehension is the definiteness of the petitions of the Lord's Prayer. Each is as clear cut as a crystal. There is no mistaking its meaning. Like the articles of the Creed they are all too simple to be vague, and they carry their meaning on their face. It is a common fault in prayer to be content with a certain comprehension that abjures definiteness. If the latter without the former can at the best make a character of but small stature, the former without the latter can make no character at all. Take the one matter of penitence. The mere admission of sinfulness, as in the prayer of the publican, is but the first moan of penitence. A riper penitence rises from the vague to the definite in declaring the sins, and not only the sinfulness, for which God's mercy is implored. True comprehension implies detailed knowledge and minute accuracy.
