Faith and Doubt
There are those who are in doubt before they deny, and there are those who are in doubt before they affirm. Those in doubt before they deny, are men who incline to a life of evil. When that life sways them, they deny things spiritual and celestial to the extent that they think of them. But those in doubt before they affirm, are men who incline to a life of good. When they suffer themselves to be turned to this life by the Lord, they then affirm things spiritual and celestial to the extent that they think of them.
