The failure of prayers of this class is due to another hidden cause. Every man has contracted debts which have to be paid; his wrong thoughts, wrong desires, and wrong actions have built up obstacles in his way, and sometimes even hem him in as the walls of a prison-house. A debt of wrong is discharged by a payment of suffering; a man must bear the consequences of the wrongs he has wrought. A man condemned to die of starvation by his own wrong-doing in the past, may hurl his prayers against that destiny in vain. The desire-form he creates will seek but will not find; it will be met and thrown back by the current of past wrong. Here, as everywhere, we are living in a realm of law, and forces may be modified or entirely frustrated by the play of other forces with which they come into contact. Two exactly similar forces might be applied to two exactly similar balls; in one case, no other force might be applied to the ball, and it might strike the mark aimed at; in the other, a second force might strike the ball and send it entirely out of its course. And so with two similar prayers; one may go on its way unopposed and effect its object; the other may be flung aside by the far stronger force of a past wrong. One prayer is answered, the other unanswered; but in both cases the result is by law. Let us consider Class B. Prayers for help in moral and intellectual difficulties have a double result; they act directly to attract help, and they react on the person who prays. They draw the attention of the Angels, of the disciples working outside the body, who are ever seeking to help the bewildered mind, and counsel, encouragement, illumination, are thrown into the brain-consciousness, thus giving the answer to prayer in the most direct way. "And he kneeled down and prayed ... and there appeared an Angel unto Him from heaven, strengthening Him."[302] Ideas are suggested which clear away an intellectual difficulty, or throw light on an obscure moral problem, or the sweetest comfort is poured into the distressed heart, soothing its perturbations and calming its anxieties. And truly if no Angel were passing that way, the cry of the distressed would reach the "Hidden Heart of Heaven," and a messenger would be sent to carry comfort, some Angel, ever ready to fly swiftly on feeling the impulse, bearing the divine will to help.
