The Sayings of the Desert Fathers
¶2. When the same Abba Anthony thought about the depth of the judgements of God, he asked, 'Lord, how is it that some die when they are young, while others drag on to extreme old age? Why are there those who are poor and those who are rich? Why do wicked men prosper and why are the just in need?' He heard a voice answering him, 'Anthony, keep your attention on yourself; these things are according to the judgement of God, and it is not to your advantage to know anything about them.'
