Those who are in love know it. The poets write about it. We even watch movies about it. But rarely do we find a church that teaches it– that is, that true love is everlasting. It cannot die. The Writings of the New Church teach that those who truly love each other will dwell together in heaven after death. Their love and their care for each other remains, and grows. Their joy in working together in service to God and to other fellow human beings flourishes, and takes on a newness each day. Swedenborg’s description of the afterlife is a complete picture and makes sense. He says that all who die enter into the other world safe and secure. Heaven is a very real world, more real than the world of appearances around us, for everything in heaven corresponds to deeper loves within ourselves. We have homes, gardens, and friends. Heaven is not a cloud upon which we sit and play harps or continually adore God through endless worship. True worship is a way of life. People are very active in heaven. Everyone there performs a function or “use” which they love to do and become more proficient in each new day, and what they do benefits everyone around them. “Heaven,” Swedenborg says, “is a kingdom of uses.”
This concept holds true of marriage as well. Good marriages are active marriages. In heaven, each partner works in harmony with the other in acts of charity and love. An idle life is not only a dull life, but it can lead to lethargy and self-centeredness. People who view life as only a means of self-fulfillment create a hell for themselves which they take with them after death. Hell is not a place of punishment where God sends a person for not following His rules. Rather, hell is a place where people freely go who have stubbornly refused to let love into their lives, and who do not wish to help others. It is a frustrating life and truly is a state of hell, for evil brings upon itself its own punishment, and a selfish life leads to dissatisfaction and eventual gloom. Those who approach marriage as a means for self-satisfaction alone will find this same dissatisfaction with their relationship, and the hell that is often created in a marriage is the product of a selfish heart that acts contrary to true marriage love. Marriage brings blessings, but the blessings come into their fullness through acts of unselfishness and charity to the neighbor.
