People who say, "God doesn't heal anymore," haven't read Hebrews 13:8. It says that Jesus is the same now as He has ever been. If He healed while He walked on this earth, He still heals today.
Most people believe it is God's will to heal some; but the big questions is, "Is it God's will to heal all?"
Some say, "Well, that can't be true because I know brother so and so, he wasn't healed." If we go by the experiences of people, we might conclude it isn't God's will to heal anybody.
We must gather together all the experiences, traditions, doctrines, theories and denominationalism and just push it aside. We must look at nothing but God's Word and find out what He says.
For example: If you wanted to know my will about something, I hope you wouldn't go ask someone who doesn't know me because it's no telling what they might say!
Most people have done just that with God. If they want to know God's will, they've gone to people who don't even know Him and asked what they think. That way we get all kinds of wild ideas, not having the slightest idea what the bible says.
So if we want to find God's will on any matter, we have to go to the bible to see what it says.
