I’m trying to point out something very precise here. It is not possible for Him to rise both “on the third day” AND “after three days exactly” (as in 72 hours). If three exact days have passed, the rising would occur on the fourth day. If He rises on the third day, “exactly” three days (72 hours) would not yet have passed.
It must be one or the other.
No, you’re not holding to what the Lord himself prophecied: “In three days I will raise it back up.”
He did say three days, and three days fits almost to the minute, since he was killed on the eve of the passover. It was prophecied that way, and it was fulfilled that way.
