Of course He does, in this life and/or at Judgment Day.
The Holy Spirit is the Restrainer of Evil. God allows evil for a purpose. We don't always see His purpose immediately. Sometimes it takes years before we see. We look back at our lives and see how evil led to lessons to learn. These are that we appreciate what good is. Without evil, we would not really know God's attributes, the fruit of the Spirit, we wouldn't understand. Mercy, forgiveness, faith, hope, peace and even love would not be understood without experiencing evil. Life would be bliss, la te da. Some children for a a while are sheltered from evil, protected, and this sheltering is actually harmful to them because they get spoiled and don't realize what they have. No parent can shelter them forever or even from their own faults and evil.
Vengeance is Mine, says the Lord!
A neighbor coveted my wife and when I was away, got intimate with her. When I returned, she gave this story of wanting to separate. Confused, I said, let's go see a counselor and keep it together. Two weeks later, a friend told me to open up my eyes, your wife is making it with Big John. The nights she claimed she was over her girlfriends house, she was in fact with him, two doors away. I looked for her car -- it was parked on the other street -- Gotcha. I chased her down that morning and ended it. Our marriage was over. Actually, the apparent evil relieved me of the burden I had with this women who was also into drugs and couldn't control her drinking either. It was like a burden lifted, it was easy to say good-bye, because I no longer had to worry about her. This fling of hers was just that and she tried to get back with me, but it was too late. Two years later, at the young age of 38, Big John died of stomach cancer. God works in mysterious ways and uses evil for a purpose and sometimes it leads to good. In her case, she went into a downward spiral for many years and learned some hard lessons, but lived.
Cancer of the stomach could be purely coincidental, or because John had committed adultery, which is a sin of course and we know that the Wages of Sin is Death (Ezekiel 18:4, Romans 6:23).
A friend of mine left a religious cult after 3 and a half years of hell. They tried to discourage him from leaving, and told him that his future partner would suffer from breast cancer (or other ailments) should he break his marriage vows inside the 'church' - As it is presumed that his new situation outside the cult would an adulterous relationship with somebody whom God did not approve.
Apparently, they cited case histories of ex-members to support their ominous warning not to leave the church.
A case in point would be the example of Steve Hassan who was a leader in the Unification Church until his road traffic accident, which rendered him unconscious with both his legs broken and in hospital.
Whilst in hospital he had no further contact with members of the cult, which enabled his dad to hire an exit counsellor to 'deprogramme' his son from the cult.
Subsequently, Steve obtained his MBA from the Harvard Business School and he himself became America's foremost exit counsellor and one of the Chief adversaries of the church.
However, he did briefly
mention that his fiance outside the church had suddenly died, which could be purely coincidental, or because he had broken his marriage vows in the cult.
Of course, the cult will use examples such as Steve as propaganda for the sake of "moral high ground", and to discourage its members from leaving the Church.
They will use Steve et al to 'demonstrate' that their leader is the "Messiah, Son of God, and the Second Coming of Christ"; since he was allegedly punished because he left the Church (in opposition to "God's will"), and the death of his spouse/fiancé simply goes to show that their god is 'real'.
However, they have never claimed that the same fate would befall everyone who left the cult - Since it is known that so called 'marriage' in the church is not legally recognized and the members are still required to undergo civil marriage to (legally) validate their union inside the cult; but some members have left the cult long before their civil union, so that not all the ex-members would be guilty of adultery should they contract relationships outside the cult.
Since Christianity teaches that "Marriage is indissoluble until death of one or both partners in the relationship", but not all these marriages are validated by civil unions, which means that they are not
de jure married.
If anything, such few cases of "breast cancer" does not serve to demonstrate that the leader of this organisation is God - Although that is what they would like to think, and they will use it as propaganda - but all it serves is to demonstrate that the real God of Christianity is sovereign, which is made manifest by such examples of divine punishment.
For the wages of sin is death - Death being figurative to denote punishment in one form or another. Ezekiel 18:4, Romans 6:23
Clearly, God's law is still to be reckoned, whether or not the marriage is contracted in the cult.
Edit: Sorry, if this seems off topic; but my point was simply to illustrate that such cases of illnesses could well be attributed to the sins of those suffering the ailments (Which implies that the God of Christianity is the ultimate cause of their punishment); but the law of God is still subject to abuse, misuse, or misinterpretation by religious sects who will try to take "credit" for such illness, and they will use it to 'prove' that their leader is the "Messiah or Second Coming of Christ etc"; but we know that this has got nothing to do with their cult, but it has everything to do with Christianity, and the idea that each person will be rewarded by their works, whether good or
evil.
