Knowledge...... It can be a good thing or a bad thing. In the Garden of Eden, Satan tempted Eve to eat of the tree of the knowledge of good and evil by telling her she would not die and that she would be like God. 2 Timothy 3:7 talks about "always learning and never able to come to the knowledge of the truth". There is knowledge that doesn't lead you to the truth.
In 2 Peter 1:2,3 Scripture tells us, "Grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord; seeing that His divine power has granted to us everything pertaining to life and godliness, through the true knowledge of Him who called us by His own glory and excellence." There is knowledge that is good.
There are lots of great sites out there and very good information about Parkinson's Disease available to educate yourself with. I think it's a very good thing to learn what you can about this terrible disease. But be careful that you don't base your hope on knowledge of man and new technologies instead of Jesus Christ. I believe that what we do know about this disease has ultimately been given to us as a gift by God. He has given hope and help through new technologies (I of all people know this) like deep brain stimulation (this surgery was the means of my freedom from many of the chains of P.D.) and the many different medications that help us to function.
There are new developments with knowledge in the realm of genetics. Do educate yourselves. But what I'm saying is don't forget where the knowledge comes from and don't confuse knowledge of the disease in the hands of capable doctors, with The God who has the answers.
Thank you, Heavenly Father, for the gifts of knowledge you have given us to help us manage this disease. Thank you for every movement I CAN make. Thank you that there is relief and help, and we recognized that You are the giver of good gifts.
