251. I will come in to him, signifies conjunction. This is evident from the signification of "coming in," as being, in reference to the Lord, to be conjoined with Him (see Arcana Coelestia, n. 3914, 3918, 6782, 6783). The Lord is conjoined with those who receive Him in heart and life, because the Lord enters or flows in into life; He enters or flows in only with those who are in a life of spiritual love, or in a life of charity; for charity is spiritual love. When that love makes a man's life, the Lord enters or flows in through it into the truths of faith, and causes man to see, or to know them; from this man has the spiritual affection of truth. It is a great mistake to suppose that the Lord enters or flows in into faith alone or into faith separate from charity with man; in such a faith there is no life, for it is like the breathing of the lungs without the inflow from the heart, which breathing would be only a lifeless movement, for the breathing of the lungs is made alive by the inflow from the heart, as is well known. This makes clear by what way the Divine proceeding from the Lord is admitted, namely, by the way of the heart, that is, of the love; whether you say the heart or the love, it is the same as the life of the spirit therefrom. Love makes man's life, as anyone may know and see if he is only wing to give thought to it; for what is a man without love? Is he not a stock? Therefore, as the love is so is the man. Love is wing and doing, for what man loves he wills and does. An idea of the good of charity and of the truth of faith may be formed from the sun's light and heat. When the light that proceeds from the sun is conjoined with heat, as in spring and summer time, then all things of the earth bud and blossom; but when there is no heat in the light, as in winter time, then all things of the earth become torpid and die. Spiritual light also is the truth of faith, and spiritual heat is the good of charity. From this an idea may be formed of the man of the church; that when faith with him is conjoined to charity he is like a garden and a paradise; but when faith in him is not conjoined to charity he is like a desert, or a land covered with snow.
