Isaiah 9:6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counselor, The mighty God, The everlasting Father, The Prince of Peace.
Yeshua (Jesus) is the Prince of Peace (Sar Shalom, in Hebrew). You may have already known that the word "shalom" means peace. But actually, it has several meanings in Hebrew. Shalom means peace, completeness, prosperity, safety, contentment, health, blessing, and rest -- and not only that. Shalom is the common word for hello and goodbye.
So, when you greet someone or bid them a farewell "shalom", what you are actually doing is speaking all those blessings upon them -- and really, speaking over them the ultimate peace, Yeshua, Himself!
'Tis the season to speak shalom over one another -- in doing so, we'll truly be His ambassador of peace in this world filled with chaos! Shabbat Shalom!
