Was Paul given a personal revelation of the gospel? Is it a reasonable conclusion that he had a better understanding of it than any of the people to whom he wrote? Yes on both counts. Did I claim that he was on some "higher plane of faith"? No. Don't be so quick to assume that I'm way off track just because my phrasing doesn't meet your approval.
Nope. There's no such thing as personal or public revelation, revelation is just revelation. Paul was only isolated because his life was in danger and even the apostles didn't trust him initially. Again, there's no such thing as private revelation that is greater than public revelation.
Paul had better understanding yes but it is not their understanding that was to be perfected, they were waiting for perfect love and 1 Cor 13 is all about love and 1 John 4 has explained what perfect love is.
No higher faith either; in matters spirituality, the one who is like a child is greater than all in the kingdom of God. So Paul being a servant would count himself the least in everything because he is called to serve.
You blithely deconstruct your own argument and don't see it. If the faith that Paul had was "perfected" as you suggest, then even Paul himself would not have spoken in tongues. If Paul's faith were yet imperfect and awaited a 1st-century completion, then that completion should be evident... and isn't. There wasn't a second round of events that made Christianity something more in the second century and beyond than it wasn't in the first century. If you think otherwise, you're welcome to identify them.
I said love is perfected and perfect love comes with Christ when He indwells them.
1 John 4:
11Beloved, if God so loved us, we also ought to love one another.
12No one has ever seen God; but if we love one another, God remains in us, and His love is perfected in us.
13By this we know that we remain in Him, and He in us: He has given us of His Spirit. 14And we have seen and testify that the Father has sent His Son to be the Savior of the world.
15If anyone confesses that Jesus is the Son of God, God abides in him, and he in God.
16And we have come to know and believe the love that God has for us. God is love; whoever abides in love abides in God, and God in him.
17In this way, love has been perfected among us, so that we may have confidence on the day of judgment; for in this world we are just like Him.
And when was this expected? it couldn't be 21st century and counting.
Heb 2:
24 And let us consider how we may spur one another on toward love and good deeds, 25not giving up meeting together, as some are in the habit of doing, but encouraging one another—and
all the more as you see the Day approaching.
......
36You need to persevere so that when you have done the will of God, you will receive what he has promised.
37For,
in just a little while, he who is coming will come and will not delay.
Which day was approaching? and did they ever got to that day? either Paul was a bad liar for telling his 1st century listeners to wait for the Lord or he was inspired by God and what he said actually happened.
I'm 100% sure that day came and from that time on, gifts ceased.
