Allah gave one book to Jesus? so where is the book? Allah is not powerful to protect his book! Allah ask you to believe in a lost book that He cannot protect? Remember Allah is all knowing...Don tell me He doesn't know if the Gospel will be lost? If it will be lost, it makes no sense for Him to send it to Jesus...

Jesus was sent ONLY FOR Israelites.
Israelites didn’t accept him. Hence why should Allah protect the Injeel given to him?
Before Question Allah, you should Question yourself why you have to accept and follow the teachings not meant for Indian, Chinese ,African or non descendants of Jacob.

It is recorded in Matthew 15: 24 “I was sent only to the lost sheep of Israel.”
