You should become humble because the good God humbled himself for you. In Scripture the diagnosis of the Divine Doctor is clear: “The beginning of every sin is pride” (Sirach 10:13). The doctor himself came to you but you ridiculed him. You murmured, “What sort of God is this? One who was born, suffered, smeared with spittle, crowned with thorns and then hung up on a cross?” Despicable soul! You see the humility of your doctor; you don’t see the pride-filled wound that he has come to cure. You are displeased with the humble doctor because he is an affront to your pride.

–Augustine, Sermon 360B.17

Ouch. In typical fashion, Augustine cuts right to the chase. What kind of patient are you being for the Divine Doctor?
