Our young people are being taught (and many of us were taught) that there is no absolute truth—something that is true all the time and everywhere whether people know it or like it.
Therefore, the need for truth is a deep need of the human soul and human society.
And Jesus came into the world to say, "I am the way, the truth, and the life" (John 14:6). Then, He arose from the dead to vindicate his claim. Jesus has a right to tell us what is absolutely true because in the resurrection God proved him to be absolutely true.
Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
