“whether there are prophecies, they will fail; whether there are tongues, they will cease; whether there is knowledge, it will vanish away” (1 Cor. 13:8). And as for the gift of healing, we read of a co-worker of Paul’s, Epaphroditus, who fell seriously ill during this time (Phil. 2:25-30) and Paul no longer had the gift of healing, and was no longer able to heal as he did only a few years earlier in Acts 28:9. The gifts of tongues, prophecy, etc. were no longer in operation by the time Paul wrote the pastoral epistles.

The sign gifts ceased at the end of the Book of Acts. WHY? 1 Corinthians 13:8-12—

“Love never fails. But whether there are prophecies, they will fail; whether there are tongues, they will cease; whether there is knowledge, it will vanish away. For we know in part and we prophesy in part. But when that which is perfect has come, then that which is in part will be done away.

“When I was a child, I spoke as a child, I understood as a child, I thought as a child; but when I became a man, I put away childish things. For now we see in a mirror, dimly, but then face to face. Now I know in part, but then I shall know just as I also am known.”

Purpose of “sign gifts” were signs for God’s “sign people”. All these gifts of the spirit served a beneficial purpose that contributed to the numerical growth of the congregation but also resulted in its spiritual upbuilding

“Many will say to Me in that day, Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ And then I will declare to them, I never knew you; depart from Me, you who practice lawlessness!'” (Matt. 7:22-23). https://www.bereanbiblesociety.org/when-did-the-gift-of-tongues-cease/
