It’s quite rare in those who are saved and it doesn’t come from being saved. It comes from seeking to know Him once saved. It comes from obeying Him. For those who come so far, being saved actually hardly matters any more.
Don't think so:
[1Co 2:13-14 KJV]
13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know [them], because they are spiritually discerned.
