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.

1304. “我们要建造一座城和一座塔” 表他们编造一种教义和一种敬拜. 这从接下来论述的 “一座城” 和 “一座塔” 的含义清楚看出来. 教会有这样的性质, 当对邻之仁离去, 我欲取而代之时, 信之教义根本没有任何意义, 只会沦为自我崇拜. 人们也不觉得敬拜有什么神圣可言, 除非它是为了自我的缘故, 因而是自我崇拜. 一切我欲都具有这样的本质. 事实上, 凡爱己过于爱他人者不仅憎恨所有不顺从他的人, 只在他们顺从时, 才会对其表现出好感, 而且若不受到约束, 还会向前直冲, 甚至凌驾于神之上. 若放任自流, 这便是我欲的本质, 这一点已实实在在向我显明. 这就是 “一座城和一座塔” 的含义. 我欲和源于它的一切恶欲是所有事物中最肮脏, 最亵渎的, 恰是地狱本身最真实的写照. 谁都能由此推断出含有此类事物的敬拜具有何种性质.
