Matthew 18:8“If your hand or foot causes you to sin, cut it off and cast it from you. It is better for you to enter into life lame or maimed, rather than having two hands or two feet, to be cast into the everlasting fire. 9 And if your eye causes you to sin, pluck it out and cast it from you.

I use to have trouble with this passage till I understood who I am in Him. In 2015 when my life turned upside down , I got sick and developed an ulcer that hurt really bad. That is when God gave me Psalm 46:10Be still, and know that I am God; . The hardest thing to do as humans is to give everything back to God. We may say we give something to Him with our mouths but our soul is still has a firm grip.
He created us and today when I heard Luke 12:7 But even the very hairs of your head are all numbered. Fear not therefore: ye are of more value than many sparrows, I wondered if we really believe this???


If you have anything going on with your body , remember it is not ours. Get on your knees and give it back to Him. I did this and it worked.
We are drowning in sickness and disease right now, we go to all kinds of things and people but I knew what was causing that burning in my gut, the worry in my head. Now I pay attention to things that get hurt or cause pain , talk to God first before anything or anyone , really talk to Him.

This is the hardest part of being human...
Luke 14:26 If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple. Do you hate all Jesus said to hate.

Why do you think satan used all he used to try and make Job not love God... Luke 13 is great about a woman in church even though she had suffered 18 years and Jesus healed her.
Verse 16 So ought not this woman, being a daughter of Abraham, whom Satan has bound—think of it—for eighteen years, be loosed from this bond on the Sabbath?”

Take all you face to the One that created you...Be willing to say as I did one day hurting beyond belief , “alright God You created this body I give it back , if You want me to suffer or even die make it for Your Glory.” Not easy to do, I know... Doing it with the mouth and not the heart does no good. Ask as I did do I believe Luke, 12 , Luke 14 or any of the Word or just to easy parts. Following Jesus is not easy and we can not even do it without drawing from the strength from God.

Also if we are praying for healing and have anything in our hearts like unforgiveness or sin we have not got rid of , He will not listen.
Ask God to pluck out anything keeping you from Him, it is not this life that matters but the next without pain and sickness but satan wants us to think different...
