Basil of Caesarea
Patristic
c. A.D. 330–379
“Since the psalmist is conscious of the use of sincere hope in God, he invites the people to a zeal equal to his own, saying, "Trust in him, all you people; pour out your hearts before him." It is impossible for us to become capable of divine grace unless we have driven out the evil passions that have preoccupied our souls. I know doctors who do not give the salutary medicines before they have drained out by means of an emetic the matter that was causing the sickness, which the intemperate had stored up in themselves through a bad diet. Perfume should not be poured into a vessel that had previously been filled with some foul-smelling liquid, unless it is washed out first. Therefore, it is necessary that its initial contents be poured out, in order that it may be able to contain that which is being brought in.”
