Prayer and fasting was a lifestyle habit that Jesus said was required for healers to adopt—in order to prescribe a cure to the most difficult evils. One glaring example of this is with the epileptic boy. The Gospel chapters of Matthew 17:14-21 and Mark 9:14-29 both confirm this healing event. Where Jesus testifies to his disciples, that in addition to faith, this type of evil won’t depart but by the virtue of prayer & fasting.
Holy Bible and ancient Chinese Medicine texts teach us this same fact: the breath of life comes from Heaven. Man knows for proper nourishment, air must pass thru the nose and into the lungs freely. Changes made to the face or body, improper diet and injury can all lead to less nasal airflow. If the nose is not clear, the breath of God cannot enter; and life will be a struggle.
The Apostle Paul wrote openly in the New Testament on the lust of the flesh and earthly desires; versus the fruit of the Spirit. And how selfish carnal cravings are contrary to the Spirit. Interestingly, ancient Chinese Medicine texts reveal a similar statement. On how pursuing vain desires and indulging in excesses cause your movements and health to weaken.
