Shavuot's Spiritual Significance
Shavuot's celebration in Jerusalem serves as the day the Holy Spirit descended upon Israel. The Holy Spirit descended upon the Israelites, giving them power to announce good news about the Messiah. The good news was that He overcame Satan, conquered death, and arose on the third day. This power manifested itself in many miraculous gifts which were evidence of God's supernatural workings among men. As in the first century, the Body of Messiah is showing renewed interest in God's supernatural power. God’s indwelling of His Holy Spirit has accelerated the harvest of souls. Shavuot at Mt. Sinai is the physical giving of the law; now we have the fulfillment of Jeremiah's prophecy through the arrival of the Holy Spirit whereupon God now writes his Law on believers hearts.
Behold, the days are coming, says the LORD, when I will make a new covenant with the house of Israel and with the house of Judah—not according to the covenant that I made with their fathers in the day that I took them by the hand to lead them out of the land of Egypt, My covenant which they broke, though I was a husband to them, says the LORD. But this is the covenant that I will make with the house of Israel after those days, says the LORD: I will put My law in their minds, and write it on their hearts; and I will be their God, and they shall be My people.
Shavuot is the time when Judaism was born, the giving of the Law of Moses.
Shavuot is also the time when the church or body of the Messiah was born.
Shavuot at Sinai represents when God instituted the Mosaic Covenant. Shavuot at Zion is the day when the Spirit of God began writing the Torah on people’s hearts. (2 Cor 3:3; Heb 8:10)
As mentioned in Leviticus, the two loaves made with fine flour and baked with leaven were waved before the Lord. The loaves symbolize how both Jew and Gentile make up the body of the Messiah.
