Jesus promised "I will never leave you nor forsake you." The good shepherd doesn't go around losing sheep. If you were truly a born again Christian, then you still are. If a soldier walks away from the military, is he no longer a soldier? No, he is still a soldier, just a very naughty one who will be disciplined. Someday, when Jesus welcomes you home, you will realize what a living testimony you were of God's Grace, Mercy and Patience. "Blessed is the man to whom the Lord will NOT impute sin." God's promises are sure and unchanging, whether you like it or not.
Wow! I think you take the prize as the most hate-filled person I've ever met. Congrats! I don't know of anyone who wants to exterminate the Muslims, certainly not Israel. I'm a Christian, yet have several Muslim and Jewish friends.
The God of the Bible is a God of Love. Our God offers forgiveness and peace through faith in the Jewish Messiah, JESUS. (not the same as "Isa" of the Koran). Jesus is God, the Creator, who became a man, and died for my sins on the cross. He took the punishment that I deserved, forgave my sins, and gave me a new life! He will do the same for you.
Will you try reading just one chapter of the Bible? (I have read almost all of the Koran.) What will one chapter hurt? https://biblehub.com/esv/ephesians/2.htm (other languages available)
