If you look back at Exodus, Moses was on the Mountain of God for 40 days and 40 nights getting the first tablets from God when the people decided that Moses was dead and wasn't coming back. They were tired of waiting. They made Aaron fashion a golden calf from their days back in the slavery of Egypt(the world). Moses came down and broke the tablets and punished the worshipers. This is a picture of the world waiting for the return of Jesus, but in the Last Days, scoffers will say where is His coming and they will get tired of waiting and accept the first counterfeit Jesus that presents himself. Moses went back up the mountain to renew the Covenant and offered to die and go to hell for the Israelites, (Jesus will be the only one allowed to do that, remember Issac was also offered up to God), and comes back down with His face glowing and new tablets. This represents Jesus' second coming after the Antichrist set up house in the 3rd Temple the Jews built. Jesus' next coming will be supernatural and everyone will know it's the true God coming in His glory. He kills 2/3 of the world and sets up a physical Kingdom and builds His own Temple, not made with human hands, as found in Eze 40-48.
Jesus was the final blood sacrifice and He is looking for sacrifices of praise and thanksgiving. Physical circumcision has been replaced by a circumcised heart. Jesus set up His Spiritual Kingdom the first time and He will come back to set up a physical Political Kingdom on earth and sit on the throne of David for 1000 years in the Last days.
There is a lot more, but most people aren't interested in what the Bible really says. The main thing to look for is the 3rd Temple will mark the arrival of the Antichrist and the church will be Raptured out before he shows up. Look how the Jews are so excited about the third Temple knowing they haven't had one for 2000 years. How did they get their sins forgiven for the last 2000 years without the Temple/priest system gone? They are blinded like Paul says in Romans. What they believe doesn't even make sense anymore. If a MAN says he is God, he is clearly NOT God. The second coming of Christ will be spectacular and every eye will see it and He clearly won't be a normal man. The Bible said Moses had "horns of light" emitting from his face so that he put a cloth over his face. That just means the light originated from him, not reflected light. The Antichrist may perform some tricks, but he has no Shekinah Glory.
The Ark was not in the Second Temple a d didn’t prevent it from being the Temple.
