Here is a must see YouTube video created by a non-Jewish Christian that staunchly defends the Star of David as a Holy Symbol of Jesus Christ. Here it is below-
The Jewish Star of David secretly honors Lucifer under the disguise of Remphan, the ancient Egyptian “Star” god. In Acts 7:39-43 the blessed martyr Stephen blasted the Jews, prophetically declaring, “Yea, ye took up the tabernacle of Moloch and the star of your god Remphan, figures which ye made to worship them: and I will carry you away beyond Babylon.”
The magi’s coming to Jerusalem in order to pay homage to the king of the Jews shows that they seek in Israel, in the messianic light of the STAR OF DAVID, the one who will be king of the nations. Their coming means that pagans can discover Jesus and worship him as Son of God and Savior of the world only by turning towards the Jews and receiving from them the messianic promise as contained in the Old Testament.
