‘I am the truth. . ..’(John 14:6)
For most of time, men and women have assumed that the truth was there to be found out. This began to change in the 19th century and the change gathered pace in the 20th. As people began to question the existence of God, it became obvious to some, that the existence of truth requires the existence of God. With God dismissed, it became impossible to conceive of truth in any absolute sense. This has resulted in the humiliation of truth. Truth is now whatever you would like it to be.
Truth's demise has filtered down through the great centers of learning, the arts, and on into streets and homes. Everything is possible with truth gone. Everything is permissible. Musicians make music that doesn't sound musical. Painters paint pictures that are incomprehensible to normal folk. Playwrights write plays that are nonsense, and architects design buildings that no one can understand. All this is put forward as legitimate, but what does it all mean?
No matter how much... popular culture---is encouraged to believe in the relativity of truth, no one can build a decent life on such a notion.
Inevitably proponents of freedom from God, and from absolute truth, are obliged to reach outside of their own system, and borrow something from theism in order to make their lives work. The person who believes that everything is valid, will soon find that he is condemned to meaninglessness. Christ is a standing offer of escape from such a hell as this To believe that truth is like Christ, is salvation indeed.
