He is looking in the wrong places for the resurrection and likely for the same reasons the various endings of Mark were added, subtracted, rewritten, supplemented, and reinserted over time, (following Mark 16:8). But he also made a mistake concerning Mark 16:1-8 by leaving out the critical account of the neaniskos-young man, and by stating that the women never entered the tomb, for those things are in the original text. Anyhow, again, he is looking in the wrong places for the anastasis-resurrection. Why do you suppose the following statement is made?
Acts 1:21-22
21 It is therefore necessary that of the men who have been with us all the time that the Master Yeshua went in and out among us:
22 beginning from the immersion of Yohanan to that day when he was taken up from us, that one of these should become a witness with us of his resurrection.
Why do they need one who was with them all the time beginning from the immersion of Yohanan if the purpose for choosing another was to be a witness of his resurrection? It is because all of the time they spent with the Master they were witnessing a resurrection in the way that Yeshua teaches the resurrection. From the record of Yohanan anyone who stands against the beast refusing to bow the knee to Baal must be slain, (Rev 13:15-18). Anyone who is not slain therefore is overcome by the beast and the devil through fear of death because he was not willing to lay down his own soul in the high places of the field. Only those who are willing to die for the truth in that hour will overcome; and for overcoming, they die, and yet live. And if they die in Messiah, and yet live, then they rule and reign with Messiah for at least a day, (for one day beside the Father with the Son may as well be a thousand years).
Mark 1:12-13
12 And immediately the Spirit ejected him into the desert.
13 And he was in the desert forty days, tempted under the Satan, and was with the θηριων-beasts, [Hosea 13:7-11, Daniel 7:1-14, Rev 13:1-18] and the Angels ministered unto him.
There was no way death could hold him because he had overcome and the flesh profits nothing to the one truly born from above. The physical death of the body counts for nothing to such a one, being in Messiah: for they cannot die any more because they are isangeloi, and are sons of Elohim, being sons of the resurrection. Therefore these things must occur before one sheds the carcass for good, (and I do believe Paul teaches the same since the day he was caught up to Paradise, [it was his twin Baal in the third heaven speaking things unlawful for an anthropos-man-faced to utter]).
