Islam means: submission to the will of God.
Jesus "peace be upon him" was no different than other prophets and messengers of God. He was selected to be a messenger to Israelites, He is one of the five Law-giving and great prophets and messengers, Almighty God revealed a Scripture to him called "Injil" or Gospel.
so WAS JESUS A MUSLIM? muslim to the will of God.
That's a very deceptive and dishonest definition. You're basically playing with words. There are significant differences between Christianity and Islam. You can't just throw the word "God" out there like everyone agrees who God is and what He wants us to do or not to do, unless you wanna play with words and deceive others...
