Absolute truth can only be known totally, perfectly, and absolutely by the transcendent being who is the origin of that truth. His creatures, by their nature as lesser beings, created by Him, can only know what He has made them capable of knowing. This is also true of their ability to perceive, reason, understand, and communicate.
Then we must factor in the effect the curse had on Adam’s progeny due to his sin in the garden. We are born enslaved to a sinful nature, and are destined to suffer injury, disease, and death due to his sin, known as original sin, and our own individual sins. Sin also has affected the way we perceive, reason, understand, and communicate. This is known as the, “noetic effect” of sin.
When we consider these two ideas, it might seem that it is impossible for us to know absolute truth. This would be incorrect. God has made us able to know of absolute truth, just not perfectly, absolutely, or totally. We can know that God exists, fire burns, and the wind blows. We can even understand how combustion works, and what the source of the wind is, but to know them as God does is impossible in our current state and even in our glorified state.
If you look at an apple on a desk, you’ll see an apple. If you use a magnifying glass, you’ll see the pores on the skin as well as the blemishes. If you use a microscope, you’ll be able to see the cells of the apple. Advanced technology allows us to look at the micros and macros of the cosmos in ways that were never before possible for us. No matter what technology we develop, we will never be able to perceive things the way that God does.
God wants us to know Him. He has given us the creation to see His work. He has given us the progressive revelation of His word for us to know Him. In the person of the Holy Spirit, He makes His word understandable to us. In the person of Christ Jesus, He has made it possible for us to be justified to Him, to be adopted as sons and daughters. The Bible says this about Jesus, “…He is the image of the invisible God…” (Col 1:15) It also says, “…For in Him all the fullness of Deity dwells in bodily form…” (Col 2:9)
If you’d like to know absolute truth, in as much as you can, I encourage you to think about your guilt as a sinner. Consider how holy God is as the sovereign Creator of everything. Think about His perfection in all of His attributes. Repent of your sins. Forsake them. Turn from them towards Christ. He is your only hope. “…let it be known to all of you and to all the people of Israel, that by the name of Jesus Christ the Nazarene, whom you crucified, whom God raised from the dead—by this name this man stands here before you in good health. “He is the STONE WHICH WAS REJECTED by you, THE BUILDERS, but WHICH BECAME THE CHIEF CORNER stone. “And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved.”…” (Acts 4:10-12) “…Behold, now is “THE ACCEPTABLE TIME,” behold, now is “THE DAY OF SALVATION”…” (2 Cor 6:2)
