Unfortunately, a commonly accepted understanding of God in Christendom is tainted by an Augustinian depiction of God as sort of a divine yin-yang, God being partly light, and is partly darkness. Well there’s a problem with that view, since:
1 John 1:5
5 This is the message which we have heard from Him and declare to you, that God is light and in Him is no darkness at all.
Most people that hold to yin-yang understanding of God’s character don’t explicitly acknowledge it as such. Instead, in essence what they say is this: that God is light, and yet he can do evil things, and when he does, they are not evil but good, since God does them with a greater good in mind. So then, God can inflict pain, harm, or disability on someone for greater good, which is usually presented as some form of “drawing one closer to him”.
There are physically handicapped people who are known in Christian circles who have attributed their disability to a direct, willful act of God, along with any positive changes in their character that followed. That’s a very misinformed outlook, and a dangerous one at that.
There are numerous problems with this view.
First, if you try to inflict pain, harm, or disability on someone, they will never want get close to you. Instead, they will run away from you as fast and as far as they can, or they will fight back with all the strength they got. Try it on a pet rat and see how far you get. Please don’t try it on humans, it’s been done, and it never worked.
Second, if that’s your view of God, and you simultaneously believe that God is love, you’ve just completely redefined what love is.
