“The task of the apologist is not simply to show that there is no hope of eternal salvation outside of Christ, but also that the unbeliever has no present intellectual hope outside of Christ. It is foolish for him to build his house on the ruinous sands of human opinion, instead of the verbal rock of Christ (Matt. 7:24-27). He needs to see that those who suppress the truth of God in unrighteousness inescapably "become vain in their reasoning… Professing themselves to be wise, they become fools" (Rom. 1:21-22). Their opposition to the faith amounts to no more than a "knowledge falsely so called" (1 Tim. 6:20-21), by which they actually "oppose themselves" in ignorance (2 Tim. 2:23, 25).”
