Many things are true, but there is only one truth. Truth is the absolute, objective, eternal reality that originates in God, is perfectly revealed in Jesus Christ, is communicated by the Holy Spirit, and is recorded in God’s Word.
You can have your own opinions, but you can’t have your own truth. You can call it truth, but it’s not. It is objective and not relative to anything.
Truth is objective and absolute and is not relative to culture, society, or historical context.
There is only one truth— THE truth, the whole truth and nothing but the truth.
This understanding explains why Christians speak of truth as objective rather than subjective.
Truth does not change with opinions, cultures, or circumstances because God does not change (Malachi 3:6; James 1:17).
The truth we are sharing is God’s TRUTH— absolute , unchanging and indisputable.
The masses of people traveling on the broad road that leads to destruction (from Matthew 7:13-14) may dispute it, but God Himself by His very nature, declares it so.
He doesn’t merely speak truth [to sanctify you; to set you apart for His purposes, to perfect you and make you holy]; His Word is TRUTH. (John 17:17); emphasis added.
“And you will know the truth, and the truth will make you free.” (John 8:32)
Does Truth Exist?
When people make claims that are contrary to Christianity, you can often detect flaws in those claims by using “The Road Runner Tactic.”
The RR Tactic shows that many claims against Christianity are logically self-defeating. It turns a claim on itself to see if the claim meets its own standard.
For example, if someone says, “There is no truth!” then you should turn the claim on itself by asking, “It that true?”
Notice: The claim doesn’t meet its own standard- “there is no truth!” is actually a truth claim. It claims to be true that there is no truth! It’s like saying “I can’t speak a word in English!” It violates the law of non-contradiction, so it can’t be true.
Relativism is self-defeating.
Relativism is the doctrine that knowledge, truth, and morality exist in relation to culture, society, or historical context, and are not absolute.
Some Say, “All Truth is Relative!”
Is that a relative truth?
No, it’s an absolute truth. In fact, there are no relative truths. All truth is absolute. Someone might say, “I feel warm right now, but people in Alaska feel cold. That’s a relative truth.” No, it’s not. If it’s really true that you feel warm, then it’s absolutely true for all people, at all times, in all places that you feel warm right now. It doesn’t matter what the people in Alaska feel.
Since you’re the referent, it’s true regardless of what others are feeling.
Some Say, “All Truth Comes from Science!”
Does that truth come from science? No, the claim is self-defeating because it’s not a scientific truth- it’s a philosophical claim. Science requires philosophy. You can’t prove the rules of science or the tools of science (such as laws of logic, the law of causality, or the reliability of observation) by running some kind of experiment. You have to assume those things are true in order to do the experiment!
Moreover, the data one gets from science needs to be interpreted. Data doesn’t interpret itself. In fact, science doesn’t say anything- scientists do. If scientists philosophically rule out intelligent causes before they look at the evidence, is it any wonder they always interpret the data to arrive at a natural cause?
Most Important Question
This is one of the most important questions you can ask someone who isn’t a Christian: “If Christianity were true, would you become a Christian?”
If the person hesitates or answers “NO,” you probably won’t make much progress offering evidence. That person doesn’t want Christianity to be true, so no amount of evidence will convince him or her.
The biblical understanding of truth is that it is objective—it does not change based on human opinion or circumstances. Here’s a concise summary of relativism with examples.
What is Relativism?
Relativism is the belief that truth is not absolute, but depends on a person’s beliefs, culture, society, or historical era. Under relativism, what is “true” for one person or group may not be “true” for another.
Examples
- Relative to culture: One culture believes there are many gods; another believes there is only one God. Relativism says both can be “true” within their own cultures. No it can’t.
- Relative to society: A society may approve of practices that another society condemns. Relativism says moral truth is determined by the values of that society. No it isn’t.
- Relative to historical context: Practices such as slavery, segregation, or child labor have been accepted in some periods and rejected in others. A relativistic view says what is morally “true” changes with the times. Truth is objective. It is always true.
Biblical Contrast
The Bible presents truth differently:
Truth is objective, absolute, eternal, and unchanging because it is grounded in the unchanging nature of God—not in human opinion, culture, society, or the passage of time.
As Jesus said:
“I am the way, the truth, and the life.” (John 14:6)
And God’s Word declares:
“The entirety of Your word is truth.” (Psalm 119:160)
From this perspective, cultures, societies, and historical periods may accept or reject the truth, but they do not create or redefine it.
