Many today believe that all truth is relative, that there is no absolute truth. But this is self-refuting, for the statement “all truth is relative” is proposed as an objectively true statement that applies to everyone. If someone were to say to you, “There is no absolute truth” then they have just made a statement that is supposed to be absolutely true. What they’re actually saying is “It is absolutely true that there is no absolute truth.” If the statement were not absolutely true, then there are some cases where “there is absolute truth.” Either way, whether they are right or wrong, the person making this statement is giving us absolute truth.
It is also popular today to say “you can’t know truth.” If someone says this to you, ask them, “that statement you just made, do you know it’s true?” Either way they answer, whether they say yes or no, it’s possible to know truth. For if they say yes, then they know a truth; if they say no, then the statement “you can’t know truth” is false and someone can know truth.
Of course, what most people actual mean is “We can know some things, like hard science. But when it comes to morality and religion, no one can be certain or dogmatic about those topics. Morality and religion are relative truths, true for one person and not for another.” This, too, is not rational. First, the only way to get this to work logically is to consider all morality as opinion, and not truth, and there is no logical reason to consider all morality and religion as mere opinion. Why could it not be in the category of truth, and therefore be true for everyone? Second, the statement “all moral and religious truths are relative” is in the category of morality and religion. The statement tries to make an absolutely true statement that applies to all morals and religion, and in doing so is self-refuting. Third, upon closer investigation, the people who make these claims actually believe in some sort of morality and some sort of belief about religion that they hold to be universally true. Typically, they just don’t want anyone to think that ours is true, but want us to think that theirs is true. These statements impose beliefs about religion on Christians, while demanding that Christians not impose their beliefs about religion on anyone else.
Another variation of this is “that is true for you, but not for me.” If they say this, ask them, “that statement you just made, is it true for everyone, or just for you?”
This reminds me of the story that Frank Turek gave…….I go to the bank and walk up to the window and say “I’d like to withdraw $1,000” but the person behind the counter says “I’m sorry, but you only have $4.27 in your account.” I could say, “well, that’s true for you, but not for me. My truth is that I can withdraw $1,000.” We never do this, nor should we. When the policeman pulls us over for speeding, we can try to say “Well, that’s true for you, but my truth is that I wasn’t speeding.” The cop is going to say “tell it to the judge, pal. Here’s your ticket.” No other part of life can we get away with “that’s true for you, but not for me.” We can’t get away with it in any other part of life because it isn’t true, it doesn’t work. If something is true, it’s true for everyone. There is no such thing as a private truth, or two contradictory situations that are both true. To make such an assertion is expressing contradictions.
Therefore when Jesus says “No one comes to the Father except through me” (John 14:6) this statement is either true or false, but it’s not true for one person and false for another, for that would be an absurdity, a non-statement.
Since so much of the rest of scripture is proven true, we can have confidence that John 14:6 is also true, and true for everyone.
