Proverbs 4:20-24

"My son, attend to my words; incline thine ear unto my sayings. Let them not depart from thine eyes; keep them in the midst of thine heart. For they are life unto those that find them, and health (Hebrew: medicine) to all their flesh.

Keep thy heart with all diligence; for out of it are the issues of life. Put away from thee a froward mouth, and perverse lips put far from thee."

The prescribtion for divine health is complete in these verses.  Taken as prescribed, faithfully and daily, you will begin to walk in a new health.

To understand how this prescription works, you must realize that the Word of God is more than just good information. It actually has life in it.
As Jesus said in John 6:63,
"It is the spirit that quickeneth [or makes alive]; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life."

Every time you take the Word into your heart, believe it and act on it, that life of which Jesus spoke, the very LIFE of God Himself, is released in you. You may have read the healing scriptures over and over again. You may know them as well as you know your own name. Yet every time you read them or hear them preached, they bring you a fresh dose of God's healing power. Each time, they bring life to you and deliver God's medicine to your flesh.

That's because
the Word is like a seed.
Hebrews 4:12 says it is "alive and full of power--making it active, operative, energizing and effective..."
(The Amplified Bible).
It actually carries within it the power to fulfill itself.

When you planted the Word about the new birth in your heart, then believed and acted on it, that Word released within you the power to be born again.
By the same token, when you plant the Word about healing in your heart, believe and act on it, that Word will release God's healing power in you.

"My son, attend to my words; consent and submit to my sayings."
Submitting to the Word means making adjustments in your life. Say, for example, you hear the Word in Philippians 4:4 that you are to "rejoice in the Lord always."
If you've been doing a lot of griping and complaining, you'll have to change in order to submit to that Word. You'll have to repent and alter your behavior.

In addition to inclining your ear to the Word of God, the Proverbs 4 prescription also says you must keep it before your eyes and not let it depart from your sight.
In Matthew 6:22-23, Jesus reveals why that's so important.
He says, "The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light. But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness!"

Your eyes are the gateway to your body. If your eye (or your attention) is on the darkness, or the sickness that is in your body, there will be no light to expel it.
If, however, the eyes of your heart are trained strictly on the Word, your whole body will eventually be filled with light, and healing will be the result.

God bless you as you incline you'r ear to His Holy Word, the Living Word , that brings Life and health, healing and salvation to all who will listen and believe, in Jesus Name amen
