The Old Testament Tabernacle and the following two Temples were definitely ordered by God to be a sanctuary for God, in order that He would dwell with His people the Jews (Ex. 25:8-9). Likewise, all of the articles in the Temple, and the garments of the priests, and the sacrifices, were typical of Christ and His work as Priest and of the coming Redeemer (Ex. 25:10-31:18). Yes, everything in the Tabernacle and the Temples pointed to Christ.
So looking back on it, as a Christian, everything about the former Tabernacle and the Temples were good and appropriate. However, now, since we know that Christ has come and has lived a sinless life and has died on the cross for our sins, there is no longer a need for the Temple as it was originally ordered by God. For Christ has come and He has fulfilled in His life and death and resurrection all of the truth that the Temple and its articles taught us about Him.
So, sadly, the Christian, even the Jewish Christian, must reject the Third Temple as something unnecessary—because Christ has come! And He has come to dwell in every heart. And now every believer is a temple! As the Apostle Paul has written, “Do you not know that you are a temple of God and that the Spirit of God dwells in you” (1 Cor. 3:16). What a marvelous thing this is. So this is why we as believers, even Jewish believers, must reject the Third Temple as unnecessary.
Now there will be a future Temple in the Millennial Kingdom. But it will be quite different. You can read about what it will be like in the book of Ezekiel (Ezek. 40-48). This Temple will reflect on what Christ has already done for us. Thus it will be a Temple of worship and praise to Christ (Read my book, The Coming Millennial Kingdom, where I write in detail about this Temple 8).
Though this coming Third Temple will have no meaning for believers, we know that it will be constructed, and all of the preparations for its construction is a sign and an encouragement for us that His coming is near.
Yes, we know from Scripture that there will be a Third Temple in place, with sacrifices and offerings at the mid-point of the Tribulation (Dan. 9:27). We also know from Scripture that we (the church) will be raptured sometime before the Tribulation, since God has not destined the church for wrath (Jer. 30:7; 1 Thess. 5:9-10; Rev. 3:10). Therefore, as we now see the great progress of the Temple, with so many of the Temple vessels made, and the blueprints of the Temple made, and most everything ready to go, this should tell us that His coming is very near. And it should greatly excite us!
Yes, the more we see bible prophecy falling into place, and the more we see the Temple progress, and even the obstacles of progress being solved, and potentially solved, this should be great news to us, as we sense His soon coming. Moreover, this excitement should draw us closer to Him in holiness and purity.
