72. The people who love the truths of the church and take part in its good activities achieve the love in marriage and can participate in it, because the Lord receives no others. These are the ones who are in agreement with Him, so He can keep them in that love. Two things make up the church and therefore heaven in a person: the truth of his faith and the good in his life. The truth of faith brings about the Lord's presence, and the goodness in one's life according to the truths of faith establishes a union with Him, and thus a connection with the church and heaven. The truth of faith brings the Lord near because it is light. Spiritual light is nothing else. The goodness of one's life establishes a union with Him because it is heat. Spiritual heat is nothing else, for it is love, and the good of life is love. Everyone knows that all light - even winter light - brings presence, and heat together with light brings union. For orchards and flower beds appear in every light, but they do not flower and fruit except when heat joins the light.
These things lead to a conclusion - that the Lord cannot supply real married love for those who only know the church's truths, but for those who know them and take part in the good activities of the church.
