Apocalypse Revealed # 102
102. "'Be faithful until death.'" This symbolizes their reception and acknowledgment of truths until their falsities are removed and seemingly eradicated.
"Be faithful until death" means, in the natural sense, that they are not to turn away from their faithfulness until the end of their life, but in the spiritual sense it means that they will receive and acknowledge truths until the truths remove their falsities and seemingly eradicate them. For the spiritual sense is rightly for people in the spiritual world, for whom there is no death. Consequently death here means the end of their temptation or trial.
We say until their falsities are seemingly eradicated, because the falsities and evils in a person are never eradicated but set aside; and when they have been set aside they appear as though eradicated, because with the setting aside of evils and falsities a person is kept focused on goods and truths by the Lord.
Numbers 18:24
24
For the tithe of the children of Israel, which they offer as a wave offering to Yahweh, I have given to the Levites for an inheritance: therefore I have said to them, 'Among the children of Israel they shall have no inheritance.'"
