The word of God that is merely read like a piece of information cannot resonate with our spirit ,it has to be adequatey internalised before it bears fruits in our lives.
Joshua 1:8
This book of the law shall not depart out of thy mouth,but thou shalt meditate therein day and night,that thou mayest observe to do according to all that is written therein: for then thou shalt make thy way prosperous ,and then thou shalt have good success.
The only way to get the word of God into our Spirit is to meditate on it.Read it slowly, repeatedly and understand it.If you are going to maximize all scriptures I recommended to you in chapter one,you've got to meditate on them and also chew them,don't just swallow it,by that you lose that taste but when you chew it,you grind it and suck out the sweetness.
Praying that the Spirit of God helps you make sense out of them.Psalm 119:144 " ....give me
understanding and I shall live" . Understanding brings out life out of an information and incurcate it into our mental faculty ,then sending it to our heart ( subconscious mind or emotions)which makes it naturally to play out in us.Our spirit is able to work with the incurcated word at this level and being empowered to fight against any sickness in us.
2 Corinthians 10:3-4
For though we walk in the flesh,we do not war after the flesh
(For the weapons of our warfare are not carnal,but mighty through God to the pulling down of strong hold)
Casting down imaginations ,and every high thing that exalteth itself against the knowledge of God,and bringing into captivity every thought to the obedience of Christ.
This scripture explains how sickness / death mindset Work in Man.Though,we are physical being but the battles against our health is not physical,so our weapon against them should not just be physical ( just medicine alone) especially for terminal cases or complicated case or cases attacking people's mind .Our weapon should as well be spiritual weapons ( the word of God & Prayers) ,this weapon has the capacity to pull down the strong holds of sicknesses and diseases.
It will cast down imagination and every high thing that exalteth itself against the knowledge of God.(Those imaginations could be Doctor's report on symptoms of sickness that has cast fear on us,that has laid firm grip on our mind and body,with which we feel weak and so sick or oppressed that we misbehave).They will be crushed by engaging the spiritual weapon of the word.
Getting the word of God into our mind through meditation will dislodge their grip on us and as we exercise our faith by believing that we are healed.
