Everyone can know the truth. When Jesus told Thomas, I am the … truth,” remember that He had begun the conversation by referring to a place of knowing and being (heaven) that would be accessible to His followers because He was going on ahead of them. And He would have us understand the same thing about truth.
There are many people in our families, neighborhoods, workplaces, and schools who do not think truth can be truly known. Sean McDowell says, A skeptic said to me one time, “You can’t know truth.” Ironically, to claim that you can’t know truth is to claim to know something about the world, namely, that truth can’t be known. But this is hopelessly contradictory. How could someone know that they can’t know truth? To those who claim truth can’t be known, I like to ask them if they have really gone on a deliberate quest for truth? Have they considered the scientific, philosophical, historical, and experiential evidence for Jesus—who claimed to be the truth?
Jesus said, “Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. For everyone who asks receives; he who seeks finds; and to him who knocks, the door will be opened.” —Matthew 7:7–8
According to Jesus, truth can be known: “If you hold to my teaching, you are really my disciples. Then you will know the truth, and the truth will set you free.” —John 8:31–32
