This is my perspective on this issue.
I come with the perspective of being a mental health provider, I work with psychiatrist who prescribe. I do not prescribe myself, but
do therapy and can diagnose, bi-polar, depression, etc. So my perspective is one of being a Christian which should be all of our foundation, and
in addition being a clinician as well. So I'm talking about a field that I have a Masters degree in and a license to practice by the Maryland Board of Social Work Examiners, as well as being a board certified supervisor.
With that said, I'm not responding to the issue of sorcery, but to the concept of medications in general. Regarding sorcery I will just say, pray and seek wisdom. The devil isn't on vacation or taking a nap in any area of this world.
So obviously many have little problems with medications for physical ailments. Taking a Tylenol for a headache, or antacids for stomach issues, etc. We know that before the advancement of modern medicine herbs were used to treat physical problems and the worked. But modern medicines were able to isolate various active ingredients in the medicine to have a more potent and powerful affect. For example, take multi-vitamins. You can eat oranges to get vitamin C, or you can get a concentrated synthetic(man made in a lab) form in a pill.
Now when it comes to medication for mental health, people start asking questions, and rightfully they should. As a professional and seeing all through the lens of the Bible, what I see is that many people are spiritually blind to the condition of their soul(mind and emotions), and often times rely on medication as a crutch. For example, many people are depressed because they don't feel the love of God or don't have a close relationship with God in times of troubles, this problem is masked by medication because it will treat the symptom but not cure the problem. I'm seeing a client now who want's to kill himself because He sees no purpose in life. And yes, He also does not believe in God, so such a client may take medications to make himself feel better, but mask the real problem which is the hungry of His soul for a healthy relationship with God.
Yes, chemical imbalances are real, but this relates back to the Garden of Eden, the truth is we all have chemical imbalances, and all of our DNA is stained because of sin, no one is perfect. You might have one protein that does not break down a certain bacteria leading to making you allergic to something. You may have weak lungs causing you to have asthma. In terms of mental health, you may have issues with your adrenaline glands due to PTSD causing you to have instant reaction to various auditory stimulus. We all have flaws in our personalities and the way we regulate our emotions(This is why we need Jesus, if we were perfect we wouldn't need Him). When this gets go a point where it affects our daily functioning, we diagnosis this as a mental disorder. Which is just a way of labeling or giving a name to a defect we have because of our inability to be healthy(mentally) in that area. Don't forget, it if wasn't for sin we would not have any mental health disorders. I know some disorders are a result of trauma(death, rape, divorce, loss job) and others are a result of being born with a certain chemical profile(austism, etc).
For example ADHD, as a school based therapist for 8 years, over 94% of all the youth that I diagnosed as ADHD, I realized that after 8 years of research were all youth who did not have a father in the home. So it wasn't such that they were born this way, but that, the absence of their father actually changed their brain chemistry to lack focus. We forget that God is able to also change our brain chemistry back to normal. Romans 12:2 says, "Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is--his good, pleasing and perfect will." Instead of being the example to the world, we Christians are often following the pattern of this world, as we jump on the medication bandwagon. Research shows that you can change your brain chemistry just through positive thinking. Your brain is constantly rewiring itself, based on what you think and do.
I'm not saying that medications for mental health are all bad. What I'm saying is this: Imagine you have acid reflex issues. The simple first step will be to ideally eat a diet low in acid and high in alkaline foods (green vegetables, etc). But instead of dealing with the source, we would rather take an acid reflex pill and continue to eat unhealthy while treating the symptom and ignoring the problem. Or an obese person instead of exercising, may want to take a pill to help them lose weight. What does the pill teach you, does it help you be in tune with your body? Do it help you to take ownership of solving problems or does it mask the problem by treating the symptom. The same is with mental health issues, at times medications may be appropriate for mental health issues, but by far and large, most of the conditions could be address either by simply growing spiritually or changing our lifestyle. For example, I work with teen girls who may be depressed, but they don't realize that they are depressed because of their promiscuous sexual behaviors which spiritually is stealing their joy, so they take a pill to solve the problem, not know that the depression is a cry of their soul pointing to a deeper problem. Sometimes God often wants us to go through issues so we can grow. So should Job had taken a Prozac pill for his depression or was it good that He wrestled with the problem of suffering so that He could learn and grow closer to God. Would Job have grown spiritually in His situation if He just took medications and ignored the deeper problem?
When you put your hand on a hot stove you feel pain, that pain is a normal reflex, built into us to make us aware that something is wrong. This is the same with our soul, excessive worrying, depression, mood issues, are signals from our soul pointing to a deeper problem that needs to be fixed. If medications were the solution Jesus would have came passing out pills to everyone. If money was the solution, Jesus would have came passing out money to all the poor. But He didn't give them all money because the issue was not physical poverty but a poverty of the spirit. But we want everything fast. And it does take time to do it the right way and we don't want to wait. It takes time to work on a marriage, but we would rather just divorce. It takes time to exercise and discipline to eat right, but we would rather just take a pill. It takes time to analyze your relationships and think about if you are harboring unforgiveness in your life or ask for forgiveness to deal with the guilt that is affecting your mood, but we would rather just take a pill. It takes time to work out the process of maturing in God but some would rather just say, we'll I'm saved so that's it.
Don't get me wrong sometimes medications can be a lifesaver in certain situations and I supported medications for some kids I worked with whose behaviors were just so violent and there were a danger to themselves and others. But while they were on the medications and being treated at the symptom level, we worked to get to the bottom to find out what the source of the problem was, so that the medication could stop, and not be a life long crutch.
Medications are good: when they allow you to get to the root of the problem, allowing you to eventually stop the medication and resume life without being dependent on a drug.
Jesus want's us dependent on him, not medications.
