Three of the temporary gifts were to cease---1. Corinthians 13:8. The total absence of tongues, healings and other signs gifts in Paul’s later, or Prison Epistles shows that they had all passed off the scene. Paul wrote in 1. Corinthians 13:9-10, “ For we know in part, and we prophecy in part. But when that which is perfect is comes then that which is in part shall be done away.” That expression “that which is perfect” does not refer to when we get to heaven, as so many think. It means that when Paul’s full revelations are all given, when the New Testament is finished, then there would be no more use of the temporary gifts. The New Testament WAS finished, and the temporary gifts DID cease.
Please note the self-contradiction contained herein. First, that in Paul's later epistles, all of the sign gifts had disappeared. Then please note that the "perfect" is being designated as when Paul's full revelations are given,
when the New Testament is finished, that being when the sign gifts cease.
The New Testament was not finished until 95 AD, about 30 years after Paul died, and yet by the time Paul was in prison, the gifts had "ceased". Which is it, please? Also, the NT as a collection was not settled as such, and canonized until 325AD, and is still in some measure contentious as to what is or is not a part of the NT.
Secondly, as noted in prior posts, the belief that it is the New Testament writings in themselves which are the "perfect" does not fit with either the word that Paul chose to use descriptively, nor does it fit with what centuries worth of noted and notable scholars cross-reference the word to.
Sign gifts had two purposes: (1) to authenticate the inspired revelations of the Apostles; (2) to prove to unbelieving Jews that “that same Jesus whom ye have crucified” is the true Messiah.
1Cr 12:7 But the manifestation of the Spirit is given to every man to profit withal.Why was not the BIBLICAL reason for the gifts given? (rhetorical question). Because the reasons given don't fit with a preconceived notion.
