Heart
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.
Isaiah 11:10-11
10
It will happen in that day that the nations will seek the root of Jesse, who stands as a banner of the peoples; and his resting place will be glorious.
11
It will happen in that day that the Lord will set his hand again the second time to recover the remnant that is left of his people from Assyria, from Egypt, from Pathros, from Cush, from Elam, from Shinar, from Hamath, and from the islands of the sea.
