Did Satan physically take Jesus to the temple when tempting him?
Put simply, we cannot be certain whether Jesus actually stood in the temple or he did so only by means of a vision. At times, both possibilities have been presented in our publications.
Consider first what the Bible record says. In his Gospel account of this event, the apostle Matthew was inspired to write: “Then the Devil took him [Jesus] along into the holy city, and he stationed him on the battlement [“parapet; highest point,” ftn.] of the temple.” (Matt. 4:5) Luke’s parallel account puts it this way: “He then led him into Jerusalem and stationed him on the battlement of the temple.”—Luke 4:9.

So the Org is saying we dont know for sure if it was just a vision or if Jesus really did appear at the temple?
