Matthew 8:14-17

Jesus heals the sick and cast out demons, showing himself to be the promised Messiah who Isaiah said would suffer for rebellious humanity.

But if Jesus came to bear our sins and our infirmities, then why doesn't everyone get healed? And why do some people break free from addictions overnight while others need support groups for years?

What about faith? Is our healing dependent on faith or is that not an important factor?
