You come asking prayer for success in an examination, and you recall that Christ promises that if we abide in Him, we may ask whatever we will. Indeed, this promise is sure, but let us examine ourselves: do we truly abide in Him? For to abide in Him is to walk even as He walked, who sought not His own will but the will of the Father. Your desire for a perfect score, you say, is not for vain glory but because you know it is possible. Yet I would ask you: is your eye single for the glory of God in this professional undertaking? Or does a secret love of this world's acclaim lurk beneath the surface? I do not accuse, I only urge you to prove your own self.
For you must know that prayer without almsgiving is like a bird without wings. The Scriptures witness that prayers and alms ascend together for a memorial before God; and fasting itself, that queen of virtues, is dead and unworthy of the name when divorced from mercy to the poor. Therefore, while you pray for success, let your hand be open wide to those in need, lest you ask amiss. The same care you give to your books, give also to the poor, and you will find that the Lord makes your study fruitful.
You speak of tiredness and bodily drain, of moving house and falling behind. But listen: many enfeeble their bodies with luxury, yet you have another infirmity, an anxious mind that drains the flesh. The soul, like a wrestling champion, must be exercised against hardship, not pampered. When the Pentathli have no antagonist, they fill a sack with sand and fight against it to build strength. So you, in your delay and weariness, have a sack of sand: use this very frustration to train your spirit in patience and trust. The body is not strengthened by constant ease; a little hardship makes it hardy. But if you sink into low spirits, your very countenance loses its bloom, and the mind is clouded for learning. Therefore, give the body its needed rest, but not its indulgence; and let the mind be renewed in the spirit of your mind, that you may put off the old man of anxiety and put on the new man of peace.
As for a practice partner, that is a good request. For as iron sharpens iron, so one man sharpens another. Yet be not anxious if no such partner appears; the Lord Himself can be your teacher if you wait upon Him in prayer and discipline. Remember that even the best household cannot stand if the father does not rule it well; and the first house you must govern is the little Commonwealth of your own soul. Bring your passions into subjection with all gravity, and the mind will become a quiet study-chamber for the Spirit.
You missed the nearest date for the exam; do not see this as a defeat but as a providence. For the continual offerings of the old law proved their own weakness because they were never finished; but Christ's one offering perfected forever those who are sanctified. So do not think that repeated attempts, in themselves, can perfect your career. Dedicate this delay to Him, and seek first His kingdom and His righteousness, and all these skills and credentials shall be added to you as He sees best. Perhaps He withholds the exam now to give you something better: a humbler heart, a stronger faith, or a more useful season of preparation. Trust in Him.
I will pray that God grants you a sound mind and a body able to serve His purpose, and that whether in success or in waiting, you may glorify Him. But pray yourself, and add alms and fasting to your prayer, and you will find that the true victory is not a perfect grade but a soul made perfect in patience. And if you attain the hundredfold, give thanks; but if not, give still greater thanks, for then God is pruning you for richer fruit. To Him be the glory in your life, now and ever. Amen.
