The True Feast of Tabernacles

The Feast of Tabernacles was part of Moses' Law. The Feast didn't exist before the Law, and it can't exist after the Law. 

There was only one authorised way to keep it - and that was the way Moses wrote to keep it. 

It was a package. You couldn't just keep part of the Feast. It was all or nothing.

The Feast had to include a sacrifice at the altar. This wasn't optional.

It had to involve Levite priests, with a proven lineage to Levi. This wasn't optional either - and it's not possible anymore since the genealogies were lost. And even if a reliable written-genealogy is discovered, the Levitical Order of priesthood has already been superseded anyway. 

It had to be in Jerusalem. But Jesus said the hour has come when the true worshipers are no longer required to go to Jerusalem to worship. As soon as you see mention in a Bible-prophecy of a requirement to go to Jerusalem to worship, you therefore know the prophecy must have found fulfilment during Old Covenant times.

There was a curse for not keeping the Feast, and there was a curse for not keeping it the way Moses stipulated. But the New Covenant eliminated the curse of the Law, Paul taught. Especially after the second coming of Christ there will be no more curse. So as soon as you see mention of a curse in Prophecy, you know it refers to Old Covenant times. 

The kingdom of God is not eating and drinking (feasting) said Paul. Physical Feasting was a shadow. 

Seeing the Feast was a shadow - even if it's a shadow of things still to come - then the fulfilment of the shadow will not involve carrying-out the shadow again, rather the fulfilment will be the living experience of the real thing.

The substance of a shadow is not more shadow! It's not even a modified shadow. It's the substance! With no part shadow.

So if the Feast of Tabernacles was a shadow of God tabernacling with us in future, then the fulfilment of the shadow will not involve repeating the shadow (the Feast) but the fulfilment will be when God literally tabernacles/dwells with us.

The fulfilment won't involve reverting back to the Old Covenant requirement of trekking annually to a physical altar in a physical Temple in physical Jerusalem where Levites will be waiting to receive our blood sacrifice, on fear of being cursed if we don't go. That was the shadow.

Rather, the fulfilment of the shadow will be the real experience of God Himself literally dwelling with us and us with Him, thanks to the once-for all sacrifice of His Son, when His Son offered Himself for us as our High Priest in the eternal priestly order of Melchisedek, not the temporary Levitical order - dwelling together in the new, heavenly, real Jerusalem, with Him forever and ever as the bride of the Lamb. 

That's what we'll be enjoying - we won't be under an obligation, on threat of a curse, to take an annual trek to Jerusalem.

We'll have no fear of being cursed - the real curse will not be for those who don't carry-out the shadow (the feast), but it will be for those who during their life-time were wicked and did not believe in Christ and His promise of tabernacling with us eternally. And that curse shall be an eternal one.

But for us who overcome, sorrow and sighing shall flee away.
