119. His Inspiration.--It was God by His Spirit who communicated this revelation of truth to Paul. Its own greatness and divineness supply the best proof that it could have had no other origin. But none the less did it break in upon Paul with the joy and pain of original thought; it came to him through his experience; it drenched and dyed every fiber of his mind and heart; and the expression which it found in his writings was in accordance with his peculiar genius and circumstances.
120. The Man Revealed in his Letters.--It would be easy to suggest compensations in the form of Paul's writings for the literary qualities they lack. But one of these so outweighs all others that it is sufficient by itself to justify in this case the ways of God. In no other literary form could we, to the same extent, in the writings have got the man. Letters are the most personal form of literature. A man may write a treatise or a history or even a poem and hide his personality behind it; but letters are valueless unless the writer shows himself. Paul is constantly visible in his letters. You can feel his heart throbbing in every chapter he ever wrote. He has painted his own portrait--not only that of the outward man, but of his innermost feelings--as no one else could have painted it. It is not from Luke, admirable as is the picture drawn in the Acts of the Apostles, that we learn what the true Paul was, but from Paul himself. The truths he reveals are all seen embodied in the man. As there are some preachers who are greater than their sermons, and the principal gain of their hearers, in listening to them, is obtained in the inspiring glimpses they obtain of a great and sanctified personality, so the best thing in the writings of Paul is Paul himself, or rather the grace of God in him.
121. His character presented a wonderful combination of the natural and the spiritual. From nature he had received a strongly marked individuality; but the change which Christianity produces was no less obvious in him. In no saved man's character is it possible to separate nicely what is due to nature from what is due to grace; for nature and grace blend sweetly in the redeemed life. In Paul the union of the two was singularly complete; yet it was always clear that there were two elements in him of diverse origin; and this is, indeed, the key to a successful estimate of his character.
122. Physique.--To begin with what was most simply natural--his physique was an important condition of his career. As want of ear may make a musical career impossible or a failure of eyesight stop the progress of a painter, so the missionary life is impossible without a certain degree of physical stamina. To any one reading by itself the catalogue of Paul's sufferings and observing the elasticity with which he rallied from the severest of them and resumed his labors, it would naturally occur that he must have been a person of Herculean mold. On the contrary, he appears to have been little of stature, and his bodily presence was weak. This weakness seems to have been sometimes aggravated by disfiguring disease; and he felt keenly the disappointment which he knew his bodily presence would excite among strangers; for every preacher who loves his work would like to preach the gospel with all the graces which conciliate the favor of hearers to an orator. God, however, used his very weakness, beyond his hopes, to draw out the tenderness of his converts; and so, when he was weak, then he was strong, and he was able to glory even in his infirmities.
There is a theory, which has obtained extensive currency, that the disease he suffered from was violent ophthalmia, causing disagreeable redness of the eyelids. But its grounds are very slender. He seems, on the contrary, to have had a remarkable power of fascinating and cowing an enemy with the keenness of his glance, as in the story of Elymas the sorcerer, which reminds us of the tradition about Luther, that his eyes sometimes so glowed and sparkled that bystanders could scarcely look on them.
