Uhm..out of curiosity, how does one fix this? If already living under the law but not becoming free of sickness. Is there anything else one''s supposed to do?
That's not an easy question for me to answer; I'd probably need some more information about your question.
But in the mean time please read this quite short piece, which speaks directly about sickness and how it relates to The Laws of God.
Then we can take it further if you like.
