that I may be away from all kinds of sickness
This is like saying "get me away from the air around me". This is what we have an immune system for. We also have scripture about keeping us healthy.
Mark 16:18New King James Version (NKJV)
18 they[
a] will take up serpents; and if they drink anything deadly, it will by no means hurt them; they will lay hands on the sick, and they will recover.”
Luke 10:19King James Version (KJV)
19 Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.
Sickness is of the enemy and Jesus has given us power over it. We also have to eat right and get away from the poisons in our food as much as possible. The food manufacturers are not interested in people being healthy, but only in their profits and bottom lines.
Hosea 4:6King James Version (KJV)
6 My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children.
There is a lot of information on the internet about food and the poisons the manufacturers put into our "food". That is knowledge and we can refuse to seek knowledge at our own risk.
There are a lot of good teachings by Andrew Wommack at awmi.net. A good one is called "God wants you well". It is about how healing has been provided to us already, but we need to know how to access it.
In the name of Jesus, I bless you with the life of God.
