Mark the Ascetic - On the Spiritual Law 78-82

78. A man advises his neighbor according to his own understanding; but in the one who listens to such advice, God acts in proportion to his faith.
79. I have seen unlearned men who were truly humble, and they became wiser than the wise.
80. Another unlearned man, upon hearing them praised, instead of imitating their humility, prided himself on being unlearned and so fell into arrogance.
