On the same subject:

[T]here is but one object in which this true comfort can be sought and found: the all-sufficient God and His blessed communion. This is the only and highest good, and apart from this good there is none other in which a wretched sinner could find this true and essential comfort for his poor soul. The soul has miseries, needs, and desires that are infinite in dimension, and everything apart from God is finite and deficient.
