The reason mind, body and spirit being connected so important has been the subject of many books and videos from various perspectives with most focusing on health. When man was created all three came together at the same time (Genesis 2:7). Mind, body and spirit are each a witness not only for overall health or joy or peace, they witness truth as well. Deuteronomy 19:15, “A lone witness is not sufficient to establish any wrongdoing or sin against a man, regardless of what offense he may have committed. A matter must be established by the testimony of two or three witnesses.”
