'Fully' in the Bible

of teaching about washings (ritual purifications), the laying on of hands, the resurrection of the dead, and eternal judgment. [These are all important matters in which you should have been proficient long ago.]

For since the Law has only a shadow [just a pale representation] of the good things to come—not the very image of those things—it can never, by offering the same sacrifices continually year after year, make perfect those who approach [its altars].

For you have need of patient endurance [to bear up under difficult circumstances without compromising], so that when you have carried out the will of God, you may receive and enjoy to the full what is promised.
