I'm pretty sure you are talking about 1 Corinthians 13:10,It was one of the "gifts" given to anointed Christians in the first century sir. It is no longer a gift since those gifts came to their end. It had its place in our history, but is no longer needed.
1 Cor 13:10,
But when that which is perfect is come, then that which is in part shall be done away.
But verse 12 is highly relevent,
1 Cor 13:12,
For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
If perfection is already come, then it must be said that we've come face to face with God and we now know ourselves as He knows us, that we are no longer looking through a dark glass, that we are no longer deceived by the devil. I don't think that is even close to the case.
That perfection will not come until Jesus returns. Until then we will be attacked daily by the devil and his system. That did not stop at some uncertain date in the first century. He is always seeking who he may devour and we dare not rely on our own power to resist those attacks. God gave us the tools in the gift of holy spirit, but it's totally up to us to utilize those tools, i.e., the nine manifestations, or not. Too bad he's deceived many who either do not know about the manifestations or who refuse to operate them in love. It's about all he has left. He knows very well when that which is perfect will arrive and he's doing his best to make the world miserable until that day when he will finally be defeated and cast into the lake of fire.
