3146. 'And gave straw and fodder to the camels' means instruction in truths and goods. This is clear from the meaning of 'straw' as the truths present in the natural man, and from the meaning of 'fodder' as the goods there, dealt with above in 3114. Since these things are meant by 'straw and fodder' it therefore follows that 'giving straw and fodder' is giving instruction in truths and goods. The purpose of that freedom is this: Possessing the affection for truth and being stirred by that affection, a person may become instructed in such a way that truths are implanted deep within him - within the spiritual man or the soul - where they are joined to good, as may be seen from what has been shown regarding freedom in 2870-2893.

[2] This is the way in which faith - that is, truth which is the truth of faith made to take root; and unless it is coupled to good in the rational the truth of faith never receives any life, nor does any fruit develop from it. For everything called the fruit of faith is the fruit of that good which is the good of love and charity coming by way of truth which is the truth of faith. Unless spiritual warmth, which is the good of love, is actively present in spiritual light, which is the truth of faith, man would be like ground frozen stiff, as in wintertime, when nothing grows, let alone bears any fruit. For just as light devoid of warmth is totally unproductive, so is faith devoid of love.

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.
