From St. Basil:

Do not lament over a responsibility transcending your strength. If you had been destined to bear the burden unaided, it would have been not merely heavy; it would have been intolerable. But if the Lord shares the load with you, “cast all your care upon the Lord” and He will Himself act. Only be exhorted ever to give heed lest you be carried away by wicked customs. Rather change all previous evil ways into good by the help of the wisdom given you by God. For Christ has sent you not to follow others, but yourself to take the lead of all who are being saved.

He will Himself act!
