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. The Valid Apologetic
The highest ideal for the Christian is not to make peace with the world, with science, with culture at any price, but to keep himself from the evil one.
Knowledge of God never needs to be instilled in people by coercion or violence, nor by logical argumentation or compelling proofs, but belongs to humans by their very nature and arises spontaneously and automatically.Reformed Dogmatics
There is no need of traditions, no need of miracles, no need of the authority of any churches, to convince a rational creature that the works of God are his, and his only; and that he is eternal and infinite in power that made them. They carry about with them their own authority. By being what they are, they declare whose they are.Of the Divine Original
General revelation is not a tool for Christians to convince people of something they do not know, but to convict them of what they do know and fail to live up to.Reformed Systematic Theology, 1:210
Shall we, by means of a power of judging implanted in our breast, distinguish between justice and injustice, and yet there be no judge in heaven?Institutes, Book 1 Chapter 5
