Introductory example:
In the book of genesis God told Adam and Eve, if you eat the apple you will certainly die.
The serpent told them they won't die but their eyes will open instead.
This tells us the serpent was telling the truth since they didn't die, but I wouldn't call God a liar either
but instead there is a hidden meaning of "death", that is one has to grasp what did God mean.
In this specific case "death" is actually spiritual death:
Spiritual death in Christianity - Wikipedia
Interpretation:
P1 - The bible (a word of God) is a locked book that needs to be unlocked to know the truth, only a correct interpretation can lead to truth
P2 - The work of the devil (the serpent) is to unravel to people what was concealed by God, and this leads to spiritual death.
Additional insight gives Proverbs 25:2:
Proverbs 25:2 NABRE - It is the glory of God to conceal a - Bible Gateway
If you click on the link above you'll see a footnote which tells that "kings" are not people in this context but literary kings.
Who are kings but those who rule over ordinary people (or group of people) in one way or another?
Ordinary people like us are obviously not kings.
Thus:
P3 - Ordinary people don't know the truth
Conclusion:
Following 3 propositions are to be taken in respect to each other:
P3 - The bible tells the truth, there is no lie in the bible
P4 - The literal meaning of the bible is not truth
P5 - Knowing the truth will cause you spiritual death
Conclusion1 - Truth is esoteric (proper to kings - royal knowledge)
Conclusion2 - Seeking to know the truth is evil
What is truth?
Debate as you please.
