Corinthians 15

2) It seems that Christ himself often used the third day. “See, I will drive out demons today and tomorrow, heal illness, and finish the work on the third day” (Luke 13; 31-33).
31 The same day there came certain of the Pharisees, saying unto him, Get thee out, and depart hence: for Herod will kill thee.
32 And he said unto them, Go ye, and tell that fox, Behold, I cast out devils, and I do cures to day and to morrow, and the third day I shall be perfected.
33 repeatedly I must walk to day, and to morrow, and the day following: for it cannot be that a prophet perish out of Jerusalem.
The “third day” in this case means immediately or soon. It means a very short time that is imminent until something is completed or finished.
(3) The third day is a wording. Often used in the Bible. Its meaning can only be determined from the relationship between the previous and next sentences. In the Bible, for example, the third day is used to indicate when God will turn an unhappy cursed time into a happy and good time. This cannot be thought of as an exact time relationship.
(4) After all, the “third day” used by Christ means immediately and soon. In particular, “rebuilding the temple on the third day” or “finishing the work on the third day” (Luke 13; 31-33) refers to a short period of time. Therefore, it is difficult to link these points with the “third day” of Christ's resurrection. If it has something to do with the resurrection, it should be more direct and easy to understand.
