In his section on prayer, Barth discusses the real basis of prayer. Before positively establishing it, he discusses those things which are not the real basis of prayer.
First off, neither our recognition of our need nor our need itself teach us to pray. Barth says,
It is not the case that need teaches us to pray. It may also teach us an anxiety that does not pray but curiously competes with a prayer which it naturally thinks rather curious itself. It may also teach defiance, cursing and scoffing. It may also teach us to beg. It may also teach resignation. At best it will teach us to work. Even deprivation of God and desire for Him can obviously lead past prayer to the strangest by-ways of individual and collective self-help. (CD, III.4 p 91)
Secondly, it is also not “awareness of the presence of all blessings and goodness in God, of their origin and emanation from Him” that “will in itself and as such lead a man to prayer . . .” Rather than being the real basis of prayer, this awareness may very well
lead us to consider that if it rests with God to give us all that we truly lack and desire, and if we may seriously assume that He really can and will do this, and actually does it, then we must obviously suppose that He knows our legitimate needs better than we do, and even before we ourselves discover or state them.
Thirdly, we cannot “maintain that, in childish defiance of all these arguments, the demand for divine help and gifts will necessarily drive man to utterance, to formal and serious petition, and therefore to prayer.” (92)
It may well turn out, and necessarily so in most cases, that in his very awareness of need man is so oppressed by the distinction and contrast between himself and God, between the majesty of God and his own unworthiness, that he hesitates to worry Him with his desires and requests. [. . .] The result of all this is that prayer is hindered , that man has not the heart really to pray, namely, to bring his desire to utterance, even though it may really be there.
Barth sees the problem with these three bases lying in the fact that with them “we simply move round in a circle, and this is not the circle of a rolling but of a stationary wheel which can never roll without outside impetus.” The basis for prayer cannot lie within us or in our own ability to recognize certain things about God or ourselves rather, “its cause must lie outside the circle.” He continues,
The real basis of prayer is man’s freedom before God, the God-given permission to pray which, because it is given by God, becomes a command and order and therefore a necessity. As he is created free before God, man is simply placed under the superior, majestic and clear will of God. He is not, therefore, asked about his power or impotence, worthiness or unworthiness, disposition or indisposition, desire or lack of desire for prayer, but only whether it can be otherwise than that God’s will shall be done by him and in him, and therefore whether he has not to pray irrespective of all possible objections and considerations. What God wills of him is simply that he shall pray to Him, that he shall come to Him with his requests. He wills this just because it is a realisation of the natural relationship between them both, between God and man. This is true as seen from man’s side. As the creature of God he can only come to God and speak with Him as a suppliant, and he is directed to do so. But it is also true as seen from God’s side. For He is the God who lets man come to Him with his requests, and hears and answers them. He is God in the fact that He lets man apply to Him in this way, and wills that this should be the case. . . . (92-93)
