[4] The Lord acts from inmosts and outmosts at the same time because only in this way are all things held in connection, for the intermediate things depend one upon another from inmosts to outmosts and are assembled in outmosts (it was shown in Part III of the treatise _Divine Love and Wisdom_ that all things from the inmost onward are present simultaneously in what is outmost ). For this reason the Lord from eternity or Jehovah came into the world and assumed and bore human nature in outmosts. He could thus be at once from firsts in lasts, and from firsts by lasts govern the whole world and so save whom He could save according to the laws of His divine providence, which are also the laws of His divine wisdom. For it is true, as Christendom knows, that no mortal could have been saved had the Lord not come into the world (see _Doctrine for the New Jerusalem on Faith,_ n. 35). For the same reason the Lord is called "The First and the Last." 125. These angelic arcana have been premised in order that it may be comprehended how the Lord's divine providence operates to unite man to Him and Himself to man. It does not act upon a particular thing by itself in man, but on all things together and from man's inmost and outmosts simultaneously. Man's inmost is his life's love; the outmosts are in the external of thought; what is intermediate is in the internal of thought (what external and internal are like with the wicked was shown earlier); from which it is plain again that the Lord cannot act by inmosts and outmosts simultaneously except together with man, for in the outmosts man and the Lord are together. Wherefore, as the man acts in outmosts, which are in his determination, being within the range of his freedom, so the Lord acts from man's inmosts and in what follows from them to the outmosts. Man does not know at all what is in the inmosts and in what follows to the outmosts, therefore is unaware of how the Lord acts there or what He effects there. But as all these things cohere as one with the outmosts, man does not need to know more than that he should shun evils as sins and look to the Lord. Only so can his life's love, which by birth is infernal, be removed by the Lord and a heavenly life's love be implanted in its place.
