Do you have faith enough to go straight to God and ask Him for wisdom to heal? Sometimes we don't get instant healing. Just like vektek was saying that it can be good to be humbled by sickness, it can also be humbling to learn to heal our bodies the way God had originally intended.
I don't claim to know exactly what God originally intended, but I talking about finding, through nature what works to heal us? Having faith and trust that if we carefully listen He will direct us and we will learn through trial and error. In time if we continue to listen carefully, we start to hear His prompting and we are given knowledge on how to take care of our problems in life.
