5879. 'Is my father still alive?' means the presence of spiritual good from the natural. This is clear from the representation of Israel, to whom 'father' refers here, as spiritual good from the natural, dealt with in 5801, 5803, 5806, 5812, 5817, 5819, 5826, 5833 (its derivation from the natural being dealt with in 4286); and from the meaning of 'is he still alive?' as the presence of that good. For when he revealed who he was Joseph thought first about his father, whom he knew to be alive. His father was therefore present in his thought at the beginning, and also constantly after that when he talks to his brothers. The reason for this is that the internal celestial, which is 'Joseph', cannot become joined to the truths in the natural, which are 'the sons of Jacob', except through spiritual good from the natural, which is 'Israel'. And once that joining together has taken place they are no longer the sons of Jacob but the sons of Israel; for 'the sons of Israel' are spiritual truths within the natural.

5806. 'And he alone is left to his mother' means that this is the only truth the Church possesses. This is clear from the representation of Benjamin, to whom 'the only one left' refers here, as new truth, dealt with just above in 5804; and from the meaning of 'mother' as the Church, dealt with in 289, 2691, 2717, 5581. With regard to the fact that this truth - represented here by 'Benjamin', and described above in 5804 - is the only truth the Church possesses, the situation is this: Such truth is truth springing from spiritual good, which is 'Israel'; and it is what 'Benjamin' represents when he is with his father, whereas truth even more interior is represented by him when he is with Joseph. The truth which Benjamin represents when he is with his father and which is called new truth is the only truth that enables a person to be a Church, for this new truth or those truths [spoken of in 5804] hold life received from good within them. That is, the person with whom the truths of faith exist rooted in good is a Church, not so the person with whom the truths of faith but no good of charity exist. With the latter person the truths are dead, even though they may have been the same truths. From all this one may see what the situation is with regard to the fact that this truth is the only truth the Church possesses.
