St. Chrysostom on this

The Christian cause is to always stand against the lusts of the flesh, the law of our Lord, given to us, must always be before us (Discourse 9 on the Book of Genesis, ch. 1).

If we maintain the right dogmas, and neglect our life, nothing will help us (Discourse 13 on the Book of Genesis, ch. 1).

Christians impute everything, like a shadow and a dream, and do not cling to anything visible (Discourse 7 on the Book of Genesis, ch. 1).

God does not want us to benefit only ourselves, but also to benefit all our neighbors (Discourse 18 on the Book of Genesis, ch. 5).

A Christian should have only two righteous reasons for sorrow, that is, when either himself or his neighbor angers God (Homily 3 to Stagirios).

The only misfortune for a Christian is to anger God (Homily 2 to Theodore the Fallen).

Christians flourish especially when they are more persecuted (Homily 2 against the persecutors of monastic life).

A Christian, for the sake of the hope of eternal blessings, must bravely bear all the evil that happens to him (Discourse 5 to the people of Antioch).

If you are a Christian, believe in Christ; if you believe in Christ, show your faith by your works (Discourse 2 to the people of Antioch).

A Christian must take care not only of his own, but also of the salvation of his neighbor (Discourse 3 on the Book of Genesis, ch. 1).

For a Christian, neither the dogmas of the right without a good life, nor the life (good) without the right dogmas are of any use (Discourse 13 on the Book of Genesis, ch. 2).

Faith alone is not enough to lead you to heaven, but it can condemn those who have a bad life even more: "But the servant who knew the will of his master, and did not do according to his will, shall be beaten with many stripes" (Luke 12:47) (Discourse 85 on the Evangelist John).
