salaam friends,
I read a philosophy book which used truth and Truth to mean different things. The first was subjective and good for only certain boundary conditions and Truth is more of the lasting, not subject to change variety. For example, "Barack Obama is president" is true, because it will at some point be false.
Truth, or The Truth, al Haqq, is one of God's names. According to sufi philosophy, these names are the active agents, the words which cause the other things to come into being. So the existance of truth and its reflection is actually proof and indication of the existance of God. Perhaps you will recognize this concept in the phrase, the truth will set you free. There are lots of those types of quotes:
45. ALAS! ALAS! O LOVERS OF WORLDLY DESIRE!
Even as the swiftness of lightning ye have passed by the Beloved One, and have set your hearts on satanic fancies. Ye bow the knee before your vain imagining, and call it truth. (Baha'u'llah, The Persian Hidden Words)
As for wisdom, what she is, and how she came up, I will tell
you, and will not hide mysteries from you: but will seek her out
from the beginning of her nativity, and bring the knowledge of
her into light, and will not pass over the truth.
(Deuterocanonical Apocrypha, The Book of Wisdom)
23:23 Buy the truth, and sell it not; also wisdom, and instruction, and understanding.
(King James Bible, Proverbs)
5:8 For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light: 5:9 (For the fruit of the Spirit is in all goodness and righteousness and truth
(King James Bible, Ephesians)
Indeed, I could go on for many quotes from many writings of many tradition.
The search for truth leads one closer to God, it is inevitable, if not perhaps always a completed journey for some in this lifetime. Those who reject truth because it conflicts with their idea of religion, well the truth will argue with them on its own until they see that God doesn't lie in scripture or in how he made the world(s).
The truth can be, or is very upsetting. Consider al Hallaj who was killed for claiming "I am the Truth".
The Master, Rumi writes, from Hallaj I learned to hunt lions, but I became something hungrier than a lion.
The Truth is like that. It is hungrier than a lion.
