Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world. (1 Peter 5:8, 9 KJV)
Don't be fooled, the devil does not have unlimited power. He has been around for a long time wreaking havoc any way he can, through sickness and disease etc (John 10:10a) however there is a limit to what he can do. For instance he is not omnipresent or omniscient , what he has in abundance are lies , trickery and cunningness (John 8:44, Ephesians 6:11, 2 Corinthians 11:3)
He can only make you sick or put disease on you if you allow him or consent to it (most times he does it by default ). You might think this is not true but I will show you.
The scripture in 1Peter 5:8-9 explains it. If you've ever watched one of those wildlife documentaries you will notice that the lion only goes for the weak prey out of the herd. That is the picture Peter is painting. If the devil is all powerful he would not 'walk about, seeking', he would just attack all and devour all, but because he doesn't have the capacity to do that he waits for his opportunity to attack the ignorant.
The second part of that scripture says you should resist steadfastly in the faith. To resist means to stand against, but do it in faith not in fear. The same thing is repeated in James 4:7. When you resist in the faith , it means you are standing against it based on the word or promises of God. 1John 4:4 says the one on the inside of you is greater, but He needs you to express Himself.
Finally, my brethren, be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. (Ephesians 6:10, 11 KJV)
When you resist in the faith you become 'strong in the Lord and the power of His might'. If you do this you will be able to look at the disease or sickness in the face and say not today, not tomorrow or ever and kick it out!
