His throne will be in the Temple, which, btw, they are already prepairing to rebuild. I believe there are already floor plans for this temple. They don't know they are currently fulfilling prophecy. Much still has to happen before his return. Jesus will be like a "thief in the night" and take away those who are chosen in Christ (the rapture), Christians who are born again by the holy spirit (to spare them the trauma of tribulation). According to prophesy, Jesus will specifically return on the mount of olives where he gave his famous sermon on the mount speech ("love your enemies etc."). It is already well known that there is a fault line on the mount of olives. According to prophecy, the earth will rumble when he stands there once again, in glory. Interesting stuff.
