Don't need apologetics or invented stories to know the difference between the Israelites and Al Qaeda. Nor, do either of us know how God will ultimately judge any individual.
And, again, you have to go back to the Old covenant/Old Testament to justify your arrogance toward God. Those were ancient times , ancient customs, Old Covenant ways of dealing with blasphemy, idolatry, immorality, etc. Today, we need to remember the and appreciate the Old and understand how it applies to the New. But, we have also chosen to accept Jesus Christ as the one who came to Earth in the form of a man so that we could understand the true nature of a God.
If you don't choose to believe in Christ, then what you say makes sense. I do choose to believe that Christ was who He said He was. Therefore I see god the way Jesus showed Him to be. Compare the Quran and the New Testament. End of story! Peace!
This is a fairly common pseudo-christian misunderstanding: that we have the new deal and are not fully under the old deal. Even a cursory reading of your Bible (without being indoctrinated by a particular religious system) would clear this up. Reflect on the words of Jesus and believe what he said. He was (and is) the direct source. His words on the law stand to this day regardless of the pablum written later for the 'Greek' masses.
