13我们都要问自己,我们在属灵上健康么?我们的肉身要健康,就需要有强壮的心。我们如果要有属灵的健康,也必须要有强壮的心。所有属灵的疾病都是出于心理的心。我们心理的心也许在不同方面出了毛病。我们在思想上、在爱恶上,或是在我们运用意志的方式上,可能都出了毛病。如果我们心理的心是健康的,牠在思想、爱恶、决断等方面就都非常活跃积极。我们的心是我们行动的机关。这意思是说,如果我们活跃积极,我们的心在心思、情感、意志上就必定是活跃积极的。但一个人的心若不活跃,我们会怀疑他在属灵上是否是活的。他若是活的,他心里为甚么没有活动?他的心既是他行动的机关,他为甚么不正常的尽功用?我能作见证,我虽然年纪老迈,但我的心非常活跃。我满了思想、感觉和意图。我的全人─灵、魂、身体─是活跃的。但这些活动的机关不是灵、魂或身体;行动的机关乃是心同三个大动脉─心思、情感、意志。
13We all need to ask ourselves if we are spiritually healthy. To be healthy physically we need a strong heart. We also need a strong heart if we are to be spiritually healthy. All spiritual diseases are of the psychological heart. Our psychological heart may be wrong in different ways. We may be wrong in our thinking, in our loving or hating, or in the way we use our will. If our psychological heart is healthy, it will be very active in thinking, loving, hating, and deciding. Our heart is our acting agent. This means that if we are active, our heart will be active in mind, emotion, and will. However, if a person is not active in his heart, we may wonder if he is spiritually alive. If he is alive, why is there no activity in his heart? Why does his heart not function in a normal way, since it is his acting agent? I can testify that, even though I am elderly, I am very active in my heart. I am full of thought, feeling, and intention. My entire being—spirit, soul, and body— is active. However, the agent of this activity is not the spirit, the soul, or the body; the acting agent is the heart with the three main arteries of mind, emotion, and will
