9400. And said, Behold the blood of the covenant. That this signifies the conjunction of the Lord in respect to the Divine Human with heaven and with earth, is evident from the signification of "blood," as being the Divine truth that proceeds from the Divine Human of the Lord (of which above, n. 9393, 9399); and from the signification of "the covenant," as being conjunction (of which also above, n. 9396). That the conjunction with heaven and with earth is signified, is because the Divine truth that proceeds from the Divine Human of the Lord passes through the heavens down to man, and on the way is accommodated to each heaven, and lastly to man himself. Divine truth on our earth is the Word (n. 9350-9362), which is of such a character that in respect to each and all things it has an internal sense which is for the heavens; and finally an external sense, which is the sense of the letter, and which is for man. From this it is evident that through the Word there is conjunction of the Lord with the heavens and with the world (n. 2143, 7153, 7381, 8920, 9094, 9212, 9216, 9357, 9396). [2] A sure conclusion from this is that without the Word on this earth there would be no conjunction of heaven, thus no conjunction of the Lord, with man; and if there were no conjunction, the human race on this earth would utterly perish. For that which makes the interior life of man is the influx of truth Divine from the Lord, because this truth Divine is the very light that lights up the sight of the internal man; that is, his understanding; and it is the heavenly heat within this light, which is love, that enkindles and vivifies the will of the internal man. And therefore without this light and heat the internal of man would become blind and cold, and would die, just as the external of man would die if deprived of the heat and light of the sun of the world. But this will appear as a paradox to those who do not believe that the Word is of such a nature; and also to those who believe that life is in man as his own, and does not continually flow in through heaven from the Lord. (That the life of man is not in himself, but flows in from the Lord, see n. 4249, 4882, 5147, 5150, 5986, 6053-6058, 6189-6215, 6307-6327, 6466-6495, 6598-6626, 6982, 6985, 6996, 7055, 7056, 7058, 7147, 7270, 7343, 8685, 8701, 8717, 8728, 9110, 9111, 9223, 9276; and that the Lord's church scattered through the whole world is before the Lord as one man, n. 9276, in like manner as is heaven, which is for this reason called the Grand Man; and that the church where is the Word is as the heart and lungs of this man; and that all outside the church live therefrom, as the members, viscera, and all the other organs of the body, live from the heart and lungs, n. 2054, 2853, 7396.)
