I found it interesting in Ezekiel that temple sacrifices will once again take place during the millennial age. Since Christ died once and for all and His work is finished, why are there temple sacrifices again?
Various explanations have been given for the resumption of animal sacrifices in the Millennium. The most popular is that they’ll serve as a memorial to the people on Earth of what the Lord has done for them. But the Bible doesn’t explain why they’ll be resumed, only that they will. And remember, they’re only for the people on Earth. There will be no such things in the New Jerusalem where the Church will dwell. In fact there won’t even be a Temple there.
