But if Alzheimers is truly caused by physical processes, how is it any different than any other physical illness? Does the behavior associated with the brain malfunctioning differ from the pain associated with, for example, a cancer?
The thing about diseases such as Alzheimer's, Parkinson's. etc., is that they often leave the victim mentally handicapped. They behave as if they have a mental disability.
For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind. Be not thou therefore ashamed of the testimony of our Lord, nor of me his prisoner: but be thou partaker of the afflictions of the gospel according to the power of God; (II Timothy 1:7,8)
Our word here for 'sound mind' is σωφρονισμοῦ and is found only here in this form. Darby translates the passage:
For God has not given us a spirit of cowardice, but of power, and of love, and of wise discretion. (II Timothy 7:7,8)
This is a godly boldness in the face of persecution. It is a spirit that allows us to answer rightly when challenged in our faith with meekness and reverence. It is addressed first to young Timothy, that he would not walk as did the ungodly youth. Proverbs 14:16 A wise man feareth, and departeth from evil: but the fool rageth, and is confident.
The word σωφρονισμοῦ (sound mind/wise discretion) has the root σώφρων and is also used only once. It is here translated as 'sober.'
The aged women likewise, that [they be] in behaviour as becometh holiness, not false accusers, not given to much wine, teachers of good things; That they may teach the young women to be sober, to love their husbands, to love their children, (Titus 2:3,4 G4998)
Notice the common theme in our two passages- one is addressed to a young man and here towards young women. The idea here is one of teaching in the sense of bringing the younger women to their senses by showing what sound thinking truly is.
