Jerusalem is the center of Judaism. It is important to Jews because it was chosen by God (Zechariah 3:2). It was the site of the Akeidah (Binding of Isaac, in Genesis ch.22) and was later the seat of the Davidic Kings, when King David, Israel's greatest king, founded the dynasty that ruled Judah for much of its history, making Jerusalem the capital of the United Kingdom of Israel during his reign and that of his son, King Solomon.
Most importantly, it was the location of the First and Second Temples, where offerings were made to God and where His presence dwelt in the Holy of Holies (1 Kings ch.8).

Each of these two opinions has its merit and supporting arguments and each is true in a sense.
