Some additional thoughts:
Comparisons are very difficult (actually impossible) since we don't see men's hearts as the Lord does and while men can be praying and fasting and appear to be very mature saints, the Lord may have a completely different opinion than we do.
An example of this would be the Ephesian church. By all accounts a very mature church, which had great revelation about the King and the Church. And there was no shortage of miracles, either.
But, in the book of Revelation, Jesus had something to say to them.
Rev 2:1 Unto the angel of the church of Ephesus write; These things saith he that holdeth the seven stars in his right hand, who walketh in the midst of the seven golden candlesticks;
Rev 2:2 I know thy works, and thy labour, and thy patience, and how thou canst not bear them which are evil: and thou hast tried them which say they are apostles, and are not, and hast found them liars:
Rev 2:3 And hast borne, and hast patience, and for my name's sake hast laboured, and hast not fainted.
Rev 2:4 Nevertheless I have somewhat against thee, because thou hast left thy first love.
Rev 2:5 Remember therefore from whence thou art fallen, and repent, and do the first works; or else I will come unto thee quickly, and will remove thy candlestick out of his place, except thou repent.
