It is said,“The Jerusalem Temple must be rebuilt before Jesus comes back.”It

The Bible doesn’t say this.  There are some people who, in past 150 or so years have built a template of eschatology through which they interpret the Bible. They project Ezekiel’s vision of rebuilding the Temple thousands of years into the future (as in any year now) but in fact, “Ezekiel’s” Temple was already rebuilt after the Babylonian exile. (Ezekiel chapters 40-43; see also the books of Ezra and Nehemiah)

Because of Jesus’ death and resurrection, there is no longer a need for the Temple and its sacrificial system. (Hebrews 10:1; Ephesians 2:14)  Instead, those who follow Jesus are “God’s temple” and “God’s Spirit lives in you”. (I Corinthians 3:16; see also Acts 17:24, I Cor. 3:17, 6:19)
