Arcana Coelestia #8708
8708. 'And the work they must do' means faith put into action. This is clear from the meaning of 'the work they must do' as action, at this point action inspired by the light of intelligence, that is, by faith since the light of intelligence holds faith from the Lord within it, dealt with above in 8707. In the measure that a person accepts the truths of faith he passes into that light and is raised to heaven. But acceptance of the truths of faith is arrived at not by simply acknowledging them but by acknowledgement linked to life, that is, by an acknowledgement of them expressed in action. This kind of acceptance is what 'the work they must do' is used to mean.
4 Mosebok 15:34
34
Og de satte ham fast; for det var ikke gitt dem noget bud om hvad der skulde gjøres med ham.
