okay. I suppose you believe Peter is the only honored with these keys, right? Did any of the others ever profess Jesus was the Christ and Messiah? God plays favorites?
The keys Peter was given were to open the 'narrow gate' accessed by the profession put in Peter's mouth by The Holy Spirit. Some want to make more of the keys than is necessary, because it is one of the foundational powers the Catholic Church (and the Mormons) have tried to claim for themselves. Nothing these 'other' imposter key holders can do will make the Holy Spirit come into the professing believer/faither. Peter opened it, and like the Rock from which water flowed in the Desert, it only need be opened once.
I believe it was the Prophet Joel who was given a vision of the state of the Saved in Christ, but it remained a mystery that The Holy PSirit would come into the believer.faither, profess er with the profession Peter uttered first before the Lord in front of others. That indwelling Holy Spirit earnest of our inheritance is what I believe makes it possible for ONLY the Saved during the Chucrh Age to be snatched away in the Rapture written of by Paul the Apostle to the Gentiles. See [ 1Thess 4: 13-17 and 1Cor 15 ]
