72. That those come into this love and can be in it, who love the truths of the Church and do its goods, is because no others are received by the Lord; for these are in conjunction with Him, and by Him can be held in this love. There are two things which make the Church and thence heaven with man: the truth of faith and the good of life. The truth of faith effects the Lord's presence, and the good of life according to the truths of faith, effects conjunction with Him and thus makes the Church and heaven. That the truth of faith effects the Lord's presence is because it pertains to light, spiritual light being nothing else. That the good of life effects conjunction, is because it pertains to heat; nor is spiritual heat anything else, for it is love, and the good of life pertains to love. It is well known that all light, even that of winter, effects presence, and that heat united with light effects conjunction; for gardens and flower-beds are seen in all kinds of light, but do not blossom and bear fruit except when heat conjoins itself to light. From the above, the conclusion is evident, that not those who merely know the truths of the Church are endowed by the Lord with love truly conjugial but those who both know its truths and do its goods.
