Arcana Coelestia #10
10. The fourth state is when he is moved by love and enlightened by faith. Previous to this he did indeed utter pious words and bring forth good deeds, but he did so from a state of temptation and anguish, and not from faith and charity.

Leviticus 14:4-7
4
then the priest shall command them to take for him who is to be cleansed two living clean birds, and cedar wood, and scarlet, and hyssop.
5
The priest shall command them to kill one of the birds in an earthen vessel over running water.
6
As for the living bird, he shall take it, and the cedar wood, and the scarlet, and the hyssop, and shall dip them and the living bird in the blood of the bird that was killed over the running water.
7
He shall sprinkle on him who is to be cleansed from the leprosy seven times, and shall pronounce him clean, and shall let the living bird go into the open field.
