Dear Seekerofvictory,
Just a brief note concerning diseases. MOST are associated with some underlying issue, such as bitterness, resentments etc. We, being made in the image of GOD are 3 parts: spirit, soul and body. (1 Thessalonians 5:23) Even doctors and much of the supporting medical community are beginning to "catch-on" to the "spirit-mind-body" connection. (The particular science is called
Psychoneuroimmunology)
Physiologically, the Limbic system is the connection from the spirit/soul of a person to the physical functioning parts. In other words, when you or me are, let's say.........rejected, this first goes through the external (eyes, ears, etc.) to the Limbic system, then to the autonomic, and sympathetic nervous system, which then affects the central nervous system, which then affects both the lymphatic and endrocrine systems (chemical release juctions) A simple demonstration of this is when you laugh at a funny movie............you laugh a lot and afterwards you "feel real good" or at peace. The reason why, is because when you laugh, your hypothalmus gland (endocrine system) releases seratonin, a hormone.
This is all designed by GOD to work "according to our image, the image of GOD". In other words, in the Gospels, Jesus was asked a very important question: What is the greatest commandment? HIS response was...."LOVE the LORD your GOD with all of your heart, with all of your mind and with all of your strength..........and the second commandment is similar............LOVE your neighbor as you love yourself. We are DESIGNED to love, that's the IMAGE OF GOD stated in Genesis.
Here's the problem however, adversely, when we hate, hold resentments, have suppressed rage, etc., etc. IT CAUSES OUR IMMUNE SYSTEMS TO SHUT DOWN! This is throughout Scripture...............ex

A merry heart does good like a medicine, but a broken spirit(heart) dries up the bones........Proverbs 17:22 (The bone marrow is where many of the cells are formed that comprise our immune system responses) So, if we are struggling with a broken heart, we've been rejected, cheated on, etc., etc. this is what causes the disease to "get a foothold"
There's volumes more to this understanding.................you called it knowledge and discernment, well it's there for you as well as anyone who really wants to know and learn. The book "A More Excellent Way" by Henry W. Wright will teach you all about it.
There are 2 really good ministries that REALLY help people get free from diseases...............
