Jew, Greek, or Gentile?

Gentiles usually in plural, goyim), meaning in general all nations except the Jews.

Of course of time, as the Jews began more and more to pride themselves on their peculiar privileges,

it acquired unpleasant associations, and was used as a term of contempt.

The word "Gentile" sometimes translates the Greek word ethnos,

which means a nation or people, specifically someone who is not Jewish

and thus could be used in the sense of a foreigner.

Because Israel is God’s chosen people,

the Jews believe that this is because they (Jews) are better than everyone else in Gods eyes.

However;

The proof of the pudding is in the eating!

(The final results are the only way to judge something's quality or veracity).

People say the proof of the pudding is in the eating to mean that something can only be judged to be good or bad after it has been tried or used.

Truth

God chose Abram (Abraham), to teach humans the correct way to live if we, the humans, ever plan on living forever with our Creator?

Knowing full well that we, the humans, will need a cattle prod now and then to keep us on the correct path.

Also knowing full well that we would need a Sheppard to heal our wounds and relive us, the humans, from our sins!

Hence the need for the ‘Cross’ (New Testament)!

In today's words, 'God' (Creator), is the teacher, 

'Mother Earth' is the school, 'Israel' (the Old Testament), is the "teaching tools' and humans are the students.
