"Hebrew," as opposed to a "Greek" mindset? What, exactly, does that mean?

The reality is, there is a major difference between the "Greek" and the "Hebrew" mindsets due to their respective ways of thinking about life, God, and Truth. Both the Hebrews and the Greeks were (and are still) "set" in their thinking about what and how they believed.

To the Hebrews (who today are more commonly known as Jews), God was an easy concept as they already believed in ADONAI-ELOHIM, who had given His Name יהוה (the Hebrew letters, Yud-Hey-Vav-Hey, most likely pronounced Yah-way) to Moshe/Moses in Exodus 3:13-15! (While there are several different transliterations of the Hebrew letters of God's Name into English, I prefer the letters "YHWH".)

The Hebrews already knew YHWH was their Creator who had given them the Torah (first five Books of the Bible containing all of God's original, Divine Instructions, without which we would have NO blueprint for moral, holy living.)

The Greeks, on the other hand, were more prone to be atheistic or agnostic. That is why Rav Shaul (the Apostle Paul) used different approaches when speaking to Greek cultures.

To reach them and their particular mindsets, he first presented a man named Yeshua (whose Hebrew name means "YHWH is Salvation") as God's Divine Messiah - who had been sent to preach and teach the Kingdom of God and His Torah, and to do everything His Father commanded; and to ultimately, martyr himself by shedding his divine blood to atone for the sins of anyone who accepted the God of Abraham, Isaac and Jacob - who gave mankind His Divine Instructions in Righteousness, without which we would have NO blueprint for moral, holy living...

Paul needed to teach the pagans about Messiah Yeshua in simple terms they would be able to understand. They needed to know that Yeshua, who came FROM YHWH (who had supernaturally placed him into womb of human virgin) had actually been revealed in the Book of Isaiah, Chapter 53:1, as the "arm of YHWH" and also as "the Word of God" in John 1:1 and 14!

The whole world needed to know that Messiah Yeshua was VERY SPECIAL in that he was not "just a man," but a DIVINE ENTITY, sent to earth as YHWH's Emissary who - like the little lambs in the first Passover when Moshe led God's people out of Egypt - was to become our Substitute.

In other words: Perfect "justice" demands the death of the sinner. But perfect "mercy" provided a substitute for the truly repentant sinner. (See Psalm 89:14)

Shaul presented Yeshua as YHWH's chosen Messenger - the ONLY "messenger" who had the ability to forgive sin - AND who (unlike all the other messengers) had YHWH's Name within his own name. (All other messengers [also known as "angels" in many Bible versions] have the title of "El" [short for Elohim, Exodus 23:20-22] within their own names: Gabri-el, Rapha-el, Micha-el....)
All of Paul's teachings HAD to be presented in simple terms that, to our modern mindsets, are often hard to understand. (Even Peter, in his time, wrote that Paul's teachings were often difficult to grasp - 2 Peter 3:15-16.)

Attempting to get across difficult Hebrew concepts was an extremely hard thing to do. Paul's job was NOT an easy one!

FOLLOWING ARE SOME EXAMPLES OF THE DIFFERENCE BETWEEN THE "GREEK" AND "HEBREW" MINDSETS...

The "Greek" mindset imagines a tattoo or something similar on the thigh of Yeshua when he returns as "King of Kings, and Lord of Lords" (Rev. 19:11-13,16). But the Hebrew mindset sees something more in line with Torah: The tzit-tzits (braid/knots/tassels) of Yeshua's tallit (prayer shawl) falling across his thighs when He returns to earth atop a white horse!

What does that mean? Well, each letter of the Hebrew alphabet has a numerical value. Consequently, the knots of the tassels on the four corners of a tallit spell out the name of YHWH....(There are actually different trains of thought about this, depending on how the knots are tied.

The Sephardics tie the knots in windings of 10, 5, 6, 5 which spells out the numeric values of "YHWH" while the Ashkenazies use windings of 7, 8, 11, 13 which, adds up to 39, which is the numerical equivalent of Deuteronomy 6:4 which cites the Shema.)

Regardless, the numeric values refer to the only ONE true Name of our ELOHIM - יהוה

Another example of a Hebrew as opposed to Greek mindset can be seen in their respective calendars/timelines. For instance, according to YHWH's Torah, a "day" is from "sunset to sunset" (Genesis 1:5) as opposed to the modern "midnight to midnight".

And He called the days of the week the "first day", "second day", etc., whereas "the world" has named its days and months after pagan gods … and paganism does NOT line up with Torah! (Unfortunately, in our modern world - most of which does NOT line up with the Word of ADONAI-ELOHIM - we are all forced to use the names everyone is used to. (I mean, just try calling your doctor's office for an appointment on the "first day of the seventh month at the sixth hour, and see how far you get with that....)

While our respective ways of thinking about life, God and the Truth might differ, it is imperative to view SCRIPTURE via the "Hebrew" mindset because YHWH originally presented His Word in the Hebrew and Aramaic (a dialect of Hebrew); NOT in any other language, where much of the original, true meanings were mistranslated, misconstrued, or downright LOST.
