It is nice to know I am not the only one to have had sciatica healed. And why should I be?
I come from a family of engineers -- but that gene skippedd me -- and you can be pretty black and white, what works and what does not thinkers. I also have lost friends and relatives and I know that it is painful. There are two ways of looking at it, and you may not accept either. One: in the Bible, Jesus wept and so it is not a sin to be devastated -- even if you ARE God Incarnate and about to call the man out of the tomb!! Death here must be seen as a sad consequence of the rebellion that occurred early on in human history.
Two: When my father was 91 he suddenly asked me why God had done nothing about Stalin. I told him that God was giving Stalin time to repent. Getting into a theological debate with a 91 year old man (who did not believe too much) is a tricky thing and so I left him with that thought. But you could also surmise that one way God has dealt with evil is to make sure we do not hang around this Big Blue Marble forever.
All the above is dependent upon a certain level of faith -- faith, for one thing, in the goodness of God, regardless of how bad the circumstances --- and maybe faith in a certain reading of things. You may not share that.
You have heard many views on this site, and I have learned things too. I have requested Hawkings A Brief History of Time from my library and hope that I will learn some new perspectives.
Have a good week.............
