Terms for Truth
The English word has developed and maintained the broadest, most general and varied usage, going beyond both Hebrew and Greek, which were already extended in connotation. It is possible to analyze and classify the special applications of the term almost indefinitely, using other terms to indicate specific meanings in special connections, e.g. loyalty (Jud 9:15); honesty (Ex 18:21); fidelity (De 32:4); justice (Ro 2:2); uprightness (Isa 38:3); faith (Isa 26:2); righteousness (Ps 85:10); reality (Joh 17:19); veracity (Ge 42:16). It is unfortunate that translators have generally adhered to single terms to represent the original words. On the other hand, they have sometimes introduced words not represented in the original, and thus unduly limited the meaning. An example is Eph 4:15, where the original meaning “being true,” i.e. in all respects, is narrowed to “speaking the truth.” Source: International Standard Bible Encyclopaedia

John 8:44 You are of your father the devil, and your will is to do your father’s desires. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies.
Ephesians 2:2 in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience
We all were born into this world where the airwaves were filled with lies. That is the realm of the devil, Satan, the father of lies. Satan has not stopped for one moment in his quest to lie to everyone in order to keep us from the truth. It is the only weapon he has in this world.
