And what you quoted ALL THAT IS in the Old Testament also readily agrees that the Old Covenant Law was not in the Heart of God for Man, because it's a ministry of death, it kills people, that is explained quite well in the New Testament as well as the Old Testament. All the wars, the atrocity that you see happened in the OT is the result of Man boasting before God that He can keep the Law when in actual fact He cannot. The result of Sin.

So what you post above so long winded testify and agrees to this.

Just a short explanation, so that you understand better;

When God first gave the 10 commandment at Mount Sinai, what do you see as a result?

Just before that Israel boasted,

Exodus 19:8 (NIV) - The people all responded together, "We will do everything the LORD has said." So Moses brought their answer back to the LORD.

And yet a Golden Calf was produced as the result of the Law Given. The very first commandment broken "You shall not have any other Gods before me". Idolatry happened. This testify the explanation in the New Testament by the spirit of God.

And you and I know that the result of Sin is death, something that the Bible and I'm sure the Koran agrees. So why did God give the Law anyway? It's explained below.
Galatians 3:19 (NIV) - Why, then, was the law given at all? It was added because of transgressions until the Seed to whom the promise referred had come. The law was given through angels and entrusted to a mediator.

Romans 5:20 (NIV) - The law was brought in so that the trespass might increase. But where sin increased, grace increased all the more,
In Plain English, what these 2 verses means is that the Old Testament Law of God was designed to show our Sin. Without the Law, we would not know Sin.

Romans 3:20 (KJV) - Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.

Is the Old Covenant Law, wrong then? The Answer is No, We just need to understand WHY it's given. It's explained quite clearly here:
Romans 7:7
What shall we say, then? Is the law sinful? Certainly not! Nevertheless, I would not have known what sin was had it not been for the law. For I would not have known what coveting really was if the law had not said, "You shall not covet."

Romans 7:8
But sin, seizing the opportunity afforded by the commandment, produced in me every kind of coveting. For apart from the law, sin was dead.
Romans 7:8 explains that the Law was designed to bring Man to the end of Himself.

So when you read and understand in this context, you will understand why the arguments brought forth in........
