Time from resurrection to ascension?
At least the time it took the eleven disciples to walk from Jerusalem to Galilee - some 60-70 miles north
- Matt 28:16-20
More than eight days (this does not include events described in the more recent addition of John's chapter 21)
- John 20:26
With the John 21 appendix, this means it was even longer as it also features a Galilean appearance. One must add to the tale at least the time it would have taken the disciples to walk there.
40 days
- Acts 1:3
However, it is made very clear that jesus rose, made all his appearances, and ascended into heaven - wait for it - all on the same day!
- Luke 24:13, 33, 36, 50
Because it says the post crucifixion events happen on the same day, Luke makes an appearance at, or journey to Galilee impossible because everything reportedly happens in the area of Jerusalem.
Remember, the disciples are told to stay there until Pentecost ( Luke 24:49 ) and at the conclusion, jesus ascends to heaven from Bethany -just outside Jerusalem- that day.
