If there is one thing that postmodernism has done, it has substantively removed any firm grasp on logical discourse. Now, one who is a proponent of relativism would argue just the opposite – postmodernism has assuaged their desire to be firm on any one thing except relativism. No one source can be credible, save the test of one’s own self-idealized version of the truth. While there are varied exceptions to this rule, such as an appeal to what can be observed, it is through the lens of observation that they build a presupposition to truth.
Inherent to this is the rather presumptuous and contradictory notion that an appeal to authority is not permissible. In example: if I were to argue that the bible holds authority over every man, regardless of his disposition to it; that would be considered ridiculous. However, it is fully allowable for them to appeal to the authority of self to say that scripture does not hold authority over them. If they do appeal to authority outside of themselves, it is to another man who holds the exact same position.
This allows for arguments to be safely contained and never progress. When this is challenged, the argument stops immediately for one important reason: there was never intent to dialogue about these issues.
Essentially, the object behind this conversation was to proselytize and convince the believer that the scriptures are flawed, if there is a god – it is certainly not the Judeo-Christian God, belief in anything outside of what is observed is folly, and etc. Whatever the primary agenda is of the one interacting, it will be the focus of the conversation. They will lead the discussion, expect the one whom they are speaking with to adhere to their own principles of discernment, and will rarely engage with what is actually presented other than to show that their way of thinking is supreme.
All men are worshippers – it is simply the object of their affection in worship that differs. The only thing one has to do in order to discern the object of their affection is to listen long enough. What is treasured will be revealed through their lips. In this case, what they worship is not a graven image – but a reflected one. They worship themselves.
So why do we press on knowing all of this? For the Christian, what is even the purpose of sharing the gospel if this is the agenda? Simply put, we move forward in obedience to the scriptures in order to marvel in a supremely sovereign Lord who has the ability to raise the dead. No amount of evidence you provide is going to be sufficient; no amount of fine rhetoric or charm you exhibit; no amount of exposing contradicting agendas in their own beliefs.
It is God who effectually wills for one to be saved – conveniently through the faithful proclamation of the word and the incredible ministry of His Spirit. This is where my Arminian friends misconceive the ministry of the Spirit upon the unregenerate. Even the term unregenerate presupposes that an outside force must operate in order for regeneration to take place. It is the gospel that saves, leaving no room for man to boast – none.
We move forward with the understanding that only the bible is the basis for rational thought; it is divine revelation and exposes flaws in worldviews. Apart from presuppositions, no one can make sense of any human experience, thus, there cannot be neutral assumptions from which one reasons as a non-Christian. In other words, the Bible formulates how we view natural evidences and it is only through the presupposition of the true God existing that one can hold a common basis of Christian Apologetics.
For the unbeliever, the observed world formulates how they view natural evidences and it is only through that lens that they are able to have common revelation extended to them. What this means is that though nature is sufficient enough to show the existence of God in the supremacy of His creation, it is only sufficient enough to condemn. It is the gospel proclaimed that saves.
There is hope in relativism – yet only in that the gospel can penetrate putrid, rotting hearts and expose the need for a Savior. Not only this, but the totality of the faith exposes the need for repentance and submission to this same Savior. The hope in relativism is not rooted in man’s ability to conquer it with wit; the hope is rooted in an active God who delights in bringing His sheep home, making the wisdom of this world into foolishness through a message that is folly to those whom are perishing.
