Abrogation means that additional rulings to the law negate or replace previous versions of the law. For example, the speed limit on Route 101 was at one time 65 MPH, but since it is now more heavily traveled, the speed limit is now 45. But who knew?
The problem in religious law is that when the law is changed you may have not heard of the changes. Islam can add a new regulation and you not know it, or perhaps even the old law may now be in force.
In practice Muslims were once peaceable, but with subsequent rulings on Jihad and the command to kill all unconverted people that they call Infidels, foreigners are in danger of death. That includes all of us in America and any non-Muslim nation, such as China.
At one time there were no child marriages for Islamic men, but now it is more common. https://www.theepochtimes.com/top-12-countries-where-girls-are-most-likely-to-be-child-brides_1481095.html
Consequently if you read the Koran you don’t get the full picture; it is full of “old rules.”. There are many other writings which post-date that book. Furthermore, anything Mohammed did is also something believers can imitate. This should help explain why the religion has become increasingly violent.
Christianity and Judaism have established law. What the Law of God says remains in effect. “I am the Lord, I change not” it says in Malachi 3:6. And “Jesus Christ is the same yesterday, today and forever.” Hebrews 13:3
A newspaper story informs us that even Christian ministers report that Islam has the same God as Christians and Jews. Absolutely not so. And if you do not believe it because the Bible says so, at least believe it because the people who murder, rape and kill in Allah’s name never use the name of the Jewish-Christian God. They are two different spirits, two different theologies and two different patterns of life and death. The differences will prove to be important as the Presidential election of 2020 gears up.
If you want a free booklet about Islam call 1-800-700-7000, the 700 Club of the Christian Broadcasting Network. It can be read in about 20 minutes and describes the origins of Islam and why it is so sex and violence oriented.
