The nature of truth has been debated since the beginning of time. In fact, for this reason I was born, and for this I came into the world, to testify to the truth. Everyone on the side of truth listens to me. Its interesting that Pilate did not wait to hear the answer to his question. I could tell you that my watch bracelet is made of 14 karat gold and sterling silver.
Truth is defined as fact or facts, matter or circumstance as it really is.
Analysis would show that there is no gold or silver in the bracelet. When we say that God is truth, we mean that what God is corresponds to what God says and does. Thus truth is the absence of all hypocrisy and pretense. Then we discover that they are bad mouthing us to someone else. What we say is not consistent with what we are.
