The Gospel is temporary, but the law is eternal and is restored precisely through the Gospel. Freedom from the law consists, then, not in the fact that the Christian has nothing more to do with the law, but lies in the fact that the law demands nothing more from the Christian as a condition of salvation. The law can no longer judge and condemn him. Instead he delights in the law of God according to the inner man and yearns for it day and night.
Apologetics cannot precede faith and does not attempt a priori to argue the truth of revelation. It assumes the truth and belief in the truth. It does not, as the introductory part or as the foundational science, precede theology and dogmatics. It is itself a theological science through and through, which presupposes the faith and dogmatics and now maintains and defends the dogma against the opposition to which it is exposed. Thus understood, apologetics is not only perfectly justified but a science that at all times, but especially in this century, deserves to be seriously practiced and can spread rich blessing all around.

there exists in the human mind and indeed by natural instinct, some sense of Deity, we hold to be beyond dispute, since God himself, to prevent any man from pretending ignorance, has endued all men with some idea of his GodheadInstitutes, 1.3.1
