And hardly do we guess aright at things that are upon earth, and with labour do we find the things that are before us: but the things that are in heaven who hath searched out?
All Commentaries on Wisdom of Solomon 9:16 Go To Wisdom of Solomon 9
Augustine of Hippo
AD 430
Precisely by the name of sweat the sacred Scripture has called suffering in general, from which no one is exempt, because, whereas some suffer from difficult operations, others do so from excruciating cures. The studies of all those wishing to learn partake of these same sufferings. And what earth gives birth to thorns if not this one, which was not made burdensome by its maker when he created the first man? Now, however, according to what was written, "a corruptible body weighs down the soul, and the tent of clay burdens the mind with many thoughts. We barely grasp earthly things and laboriously discover what is at hand." Whether or not, then, the doctrines that a person studies are useful, it is necessary that he suffer, since a corruptible body weighs down the soul. For him too, this earth gives birth to thorns. Nor can one say that the rich are exempt from these thorns, especially since in the Gospel the thorns that suffocate the seeds that were sown, so they do not reach fruitfulness, were explained by the teacher-God as the cares of this life and anxiety over riches.
