The heart means love. A good heart means love to the Lord and to the neighbor, while a hard or stony heart means the love of self or the world -- riches and things. When the psalmist asks the Lord to search his heart, he wants the Lord to see what it is that he loves. And we are what we love. What we eat may form our earthly body, but it's only temporary, what we love forms our spiritual body, beautiful or ugly as we have chosen. It's interesting to note that the first multi-cellular motion of our embryo is the pulsating that starts in a twist of blood vessel that is to become our heart, and the last motion of our natural body is our heartbeat. It is there for all of our natural life. And of course there is a beating heart in our spiritual bodies when we come to put them on.

2322. That 'Sodom' means the evil, especially those inside the Church, is clear from the meaning of 'Sodom' as evil that stems from self-love, dealt with in 2220, 2246. It means therefore people who are governed by such evil. People who understand the Word purely from the sense of the letter may imagine that 'Sodom' is used to mean a certain kind of foul behaviour that is totally unnatural, but in the internal sense 'Sodom' means evil that springs from self-love. Out of this evil all evils of every kind well up. And the evils that well up from it are in the Word called 'adulteries' and are described as such. This will be clear from those places in the Word which will be quoted at the end of this chapter.
