To miss this key concept is to actually miss what is necessary for a meaningful relationship with God. Especially don't let the physical world determine the value of your spirit's feelings. Those emotional feelings reveal your spirit's condition and how the physical world is influencing it's existence. The essential factor necessary for a successful life is understanding that emotional feelings are the expressions of a person's spirit.
Emotional feelings are the voice of the human spirit.
Without this understanding, heart to heart or, more accurately spirit to spirit relationships are not possible. Imagine the serious consequences if we are not taught to thoughtfully consider and highly value emotional feelings. Most people do value physical feelings. If someone's tooth ached unbearably, if they were suffering from a sharp eye irritation, if their stomach was in agony, no one would ignore that pain or condemn them for wanting it to be cared for. The spiritual being is more important than the physical being.
