The Feast of Tabernacles is God's defining statement to mankind that His way can and indeed really does work.
In Deuteronomy 16:13-15, Leviticus 23:34-39 we see God's instructions to His chosen people concerning the specifics of this appointed time. As we observe these special times today as the church of God, we do so in the light of His revelation of Christ's fulfillment of all the offerings that God requires. We do so in the knowledge that this Feast points to the reign of Christ on this earth for a thousand years (Revelation 20:4), at which time God will make known to mankind that His way can, and does indeed work. For those of you that are really concerned about doing the will of God, regardless of what others may say, I encouraged you to read Zechariah 14:1,16-19.
May God bless you and grant you understanding of His Feast of Tabernacles.
