Faith has to do with hearing what God wants us to do in the various decisions pertaining to this life.
The Bible shows us a medical doctor in the church. Paul called Luke the "beloved physician". Col. 4:14
When you are sick, when there is a need for help, you might have to go to a medical doctor. It is not weak faith to do so. We pray, asking God what to do, and we try to do what we believe God shows us to do.
About 6 years ago, the eye doctor who fills the prescriptions for my eye glasses said he thought I might have glaucoma. He wanted me to see a specialist. I prayed much about what to do. Finally, I made the decision based on "peace". When I thought of not going to doctor over this matter, I had no peace, and was very troubled. I went to specialist and he said I have glaucoma. I've been going to doctor every 4 to 6 months since this time and the eye pressure has been controlled by eye drops.
At one point, eye doctor frightened me very much. I turned to God with the fear that I might lose my vision. God settled me by giving me an example of 3 elderly people I knew and none of them lost their vision though they each had eye disease. I felt God was showing me I would not lose my vision. Later we discovered the machine doctor had which caused him to question my "vision loss" was likely faulty. When another doctor gave me same tests on newer machine, these tests did not show the vision loss of the previous machine.
Recently I had bladder infection ... much discomfort. I prayed much about this, what to do? The problem stopped completely. But it returned a few days later. Then it stopped again. Then it returned again. At that point I decided to go to medical doctor. I was praying all during these weeks of dealing with the subject. I thought I might go to one of the many clinics where you just walk in without appointment and wait to see doctor. I prayed. Then I had the impression to call the doctor I have gone to for sleeping pills. I also felt it might be easier on me to go to appointment rather than to go to clinic where I might have to wait for hours to see a physician. I felt this information was from God. So that morning I called doctor's office and asked if I could get in to see him that afternoon. He could see me at 3 pm at same day. This is what I did. I believed it was God leading me to go this way so I had faith to go to medical doctor.
Faith is simply praying, asking God what to do, and then doing what you feel God shows you to do.
