Why the Mitzvah of First Fruits Only Applies After 14 Years of Conquering and Division of the Land of Israel

QUESTION: Why does the Mitzvah of “First Fruits” only apply after 14 years of conquering and division of the land of Israel? (Thus, those that had First Fruits during those first 14 years were unable to make public declaration of their faith and thanksgiving to HaShem during that period.)

ANSWER: The bringing of the First Fruits began only after the complete good in inheriting the land (and not just entering the Land); complete good could only happen after everyone received their portion. This concept of total unity of Ahavas Yisrael is also reflected by both luminaries of Chai Elul, Baal Shem Tov and Alter Rebbe.
