You ask prayers for this woman, and it is good to flee to the mercy of God, for prayer is a mighty weapon. Yet consider what the divine Scriptures teach us: the prayer of the Church availed for Peter when he was in prison, but Peter himself was also vigilant and ready to suffer for Christ. If the sick woman sleeps in her soul, if she does not herself cry out to the Lord with the blind men of Jericho, "Have mercy on us," then my prayers and yours, though multiplied, profit little. We must not place ourselves where we need not the help of others, but all of us, even the holiest, need the prayers of the saints, and more still we need our own hearts awake.
Do not say, "What need have I of prayer?" Neither Paul nor Peter said such a thing. Therefore, let her lift up her own voice to the Physician of souls and bodies. Let her not merely desire a certain number or a certain percentage of function, but surrender herself wholly to His will, trusting that He who formed the kidneys knows what is best for her salvation. The Lord Jesus, when He stood before the tomb of Lazarus, gave thanks to the Father, not because He lacked power, but to show that His will is one with the Father's.
He did not pray as a servant begging from a master, but as the beloved Son showing that all He does springs from that eternal love. We, however, are beggars, and our prayer must be the cry of the publican: "God, be merciful to me a sinner." You say she does not deserve this affliction, but who among us deserves anything but chastisement? All have sinned and fall short. The wonder is not that some suffer, but that any are spared.
Yet God's mercy is great, and He often delays judgment to lead us to repentance. So I will pray with you, but let us pray not for a mere number, as if commanding the Almighty, but that His mercy may restore her according to His wisdom, and that through this trial her soul may be drawn nearer to the eternal life that alone is secure. Go, then, to your prayer early in the morning, and bring her also, if she is able, to the spiritual warfare. For every day is a tempest, and we need the favorable winds of supplication lest we sink.
And remember: the crowds who followed Jesus cried out, "Son of David, have mercy," and their very loudness showed their earnestness. Let your prayer be loud in faith, not in noise, and trust the Lord to hear, not because we name a number, but because He is good and loves mankind.
