In the New Testament, ἀλήθεια (alétheia) is used to denote truth in a variety of contexts, including the truth of God, the truth of the Gospel, and the truth as a moral and ethical standard. It signifies not only factual correctness but also sincerity, integrity, and faithfulness. Alétheia is often contrasted with falsehood and deception, emphasizing the divine nature of truth as revealed in Jesus Christ and the Scriptures. (Bible > Strong’s > Greek > 225, Bible Hub)
