I think so. Each culture has a different perspective. The same question could be asked of God. Is he the same as Allah or the Native American Great Spirit. Family members, friends, colleagues, Hubbers who know me, all have a different perspective/interpretation of who I am, because they all see a different picture, different behaviours. Sounds reasonable to assume the God is no different.
I have other sheep that are not of this sheepfold. I must bring them also. They too will listen to my voice, and there shall be one flock and one shepherd.
So these other sheep must have been Romans, Persians, Greeks, Arabs, Asians, Africans, Native Americans, Australian Aborigines,,,,,,,, So although the gospel had not been preached to the Gentiles, still at that time in the present tense when He spoke, He included them.
