In this world of over the counter, prescription, hollistic, and natural medicines people tend to forget the potent and effective medicine of all. God! There are many promises of scripture that shows that God loves us and wants us healed! Just a few, Psalm 103:3, Isaiah 53:5, and 1Peter 2:24.
Christians do know this but tend to forget it especially when they feel what's ailing them is minor. A constant headache is most often masked with asprin that can deterioate the stomach, or Ibuprofen that slowly damages the liver. With doctor visits becoming more financially outrageous and insurance premiums on the rise, people still feel the need to run to their doctor first.
I am not condemning doctors or saying Christians should never take medicine but I believe if we turn to God first, we would find that the use of medicines and doctors are unecessary. If we turn to God with faith and believe in His power to heal us, we will realize that nothing is stronger or better . I also believe that God will speak to you and guide you to what you need to do for a sickness. I was reading Tammy Faye's (a famous christian actress aflicted with cancer) website, http://tammyfaye.com, and she was talking about how she seeks the Lord for her healing and seeks chemotherapy when He deems it necessary. She also stops chemotherapy(without her doctor's full consent) and that has actually helped her and prevented some serious consequences of too much radiation in her body. I know that God gives doctors their knowledge and He helps to create medicines for us but I believe tha t God wants us to seek Him before we seek anything or anyone else.
In 2nd Chronicles 16:12-13 we find King Asa who found consequences for not seeking out the Lord first in his trials of healing (amongst other things in his reign.), " In the thirty-ninth year of his reign Asa was afflicted with a disease in his feet. Though his disease was severe, even in his illness he did not seek help from the LORD, but only from the physicians. Then in the forty-first year of his reign Asa died and rested with his fathers." It's not that he was punished for seeking out physicians it's that he did not seek help from the Lord. He didn't believe in the power that God had. Because if he did, he would've went to Him first.
