We live in such a world today that it's hard to know whether today's truths are true at all because tomorrow it might have become a different truth. So much is relative to what people want to think is truth, and like the weather it changes all the time. This is confusing and confounding, and adds to our frustrations with life (whether we realise it or not).
However, Jesus spoke about truth; a truth that does not change on the whim of man or on how many believe it or on success or failures. The truth Jesus offers us is one that sets us free. It does not depend on what we think or believe but simply on who God is.
"Then you will know the truth. And the truth will set you free." John 8:32
Truth is not determined by how many people believe it.
