'Real' in the Bible

but now [that extraordinary purpose and grace] has been fully disclosed and realized by us through the appearing of our Savior Christ Jesus who [through His incarnation and earthly ministry] abolished death [making it null and void] and brought life and immortality to light through the gospel,

and are always learning something new, and yet are never able to arrive at real knowledge of the truth.

And just as Jannes and Jambres withstood Moses, so also these false teachers withstand the truth--being, as they are, men of debased intellects, and of no real worth so far as faith is concerned.
