ἀλήθεια
alḗtheia · noun · “truth”
Alētheia means truth — reality as it actually is, and in John, the truth embodied in Jesus, who is “the truth” and whose word sets people free.
Alētheia is truth in the sense of what is real and reliable, the opposite of falsehood and pretense. The Bible treats truth not as cold data but as something to be done and lived in.
Jesus startlingly identifies truth with himself — “I am the way, and the truth, and the life” — and promises that “the truth will set you free.” To know the truth, biblically, is finally to know him.
