The festival of Sukkot or Tabernacles (also commonly called Booths) begins on 15 Tishri and is intended to commemorate the time that the Ancient Israelites spent in the wilderness after the Exodus. Images of the post-Exodus period, God wanting Israel to remember what happened in the desert, and perhaps most importantly the need for His people to physically be reminded of His desire to commune with them, are all themes that are seen throughout one’s observance. The Feast of Tabernacles was considered to be so important in the Torah, that God gave it the distinction of being one of the three times of ingathering, along with Passover and Shavuot (Leviticus 23:39-43).
The Day of Atonement for Messianics can equally be a challenge, because of a possible emphasis on celebration at Yom Teruah/Rosh HaShanah, instead of a serious attitude and call to reflection from the sounding of the shofar. Many Messianics likewise have difficulty reverently focusing on their relationship with the Lord, and in considering where they need to improve in their spiritual walk. For us, while recognizing that our ultimate forgiveness is indeed found in Yeshua, we still need to know that we are humans with a fallen sin nature, and that we need the Lord to empower us for good works. We need to be reminded that without Him, we are nothing, and we need to intercede for the salvation of others.
There is a great deal of significance attached to this day in Jewish theology, as it is most often emphasized as a time when God looks down from Heaven and reconsiders where He stands with people. It is a time where we are to rejoice and celebrate, remembering His goodness to us, but also begin a sober examination of our humanity, and consider faults and sins that must be rectified.
