Spiritual life is acquired solely by a life according to the commandments in the Word. These commandments are given in summary in the Decalogue, namely, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not kill, Thou shalt not bear false witness, Thou shalt not covet the goods of others. These commandments are the commandments that are to be done, for when a man does these his works are good and his life is spiritual, and for the reason that so far as a man shuns evils and hates them so far he wills and loves goods." Emanuel Swedenborg was a Swedish scientist, philosopher, Christian mystic and theologian. Swedenborg had a prolific career as an inventor and scientist.
