510. [verse 11] 'And after three days and a half the spirit of life from God entered into them, and they stood upon their feet' signifies that these two Essentials of the New Church, at the end of the former [Church] while the New Church is beginning and progressing, will be made living with those who receive. By 'three days and a half' is signified to the end and the beginning (n. 505), thus from the end of the Church that exists at present to the beginning of the New, this [being with those] among whom the New Church is beginning and progressing, because it is said now of the witnesses that 'the spirit of life entered into them and they stood upon their feet'. By 'the spirit of life from God' is signified spiritual life, and by 'to stand upon their feet' is signified a natural life agreeing with spiritual life, and thus made living by the Lord. This is signified because by 'the spirit of life' is understood a man's internal, which is called the internal man, and this regarded in itself is spiritual, for the spirit of the man thinks and wills, and to think and will in itself is spiritual. By 'to stand upon the feet' is signified the man's external, which is called the external man, and this in itself is natural, for the body speaks and does what its spirit thinks and wills, and to speak and do is natural. That 'the feet' signify natural things may be seen (n. 49, 468). [2] What specifically is understood by this shall be stated. Every man who is being reformed is reformed first as to the internal man, and afterwards as to the external. The internal man is not reformed by simply knowing and understanding the truths and goods by means of which the man is saved, but by willing and loving them; but the external man [is reformed] by speaking and doing the things that the internal man wills and loves, and in so far as he is doing this, so far the man is being regenerated. He is not being regenerated before, because his internal is not in the effect before but only in the cause, and the cause, if it is not in the effect, is dissipated. It is like a house founded upon ice, which sinks to the bottom when the ice is melted by the sun; in a word, it is like a man without feet upon which he may stand and walk. The case is similar with the internal or spiritual man if it is not founded in the external or natural. This then is what is signified by the fact that the two witnesses 'stood upon their feet' after 'the spirit from God entered into them'; and what is signified also by the similar things in Ezekiel:-
