Christians who develop an interest in apologetics often begin to believe that the most important things to learn are logic, rational arguments, and evidential proofs. They can become very focused on making sure their logic is airtight, while completely ignoring the importance of the moral quality of their life. Historically, however, Christian apologists never separated rational arguments from their moral and ethical lives.
The 2nd century apologist, Athenagoras, challenged those who put too much stock in philosophy and logic, while ignoring their character. He noted that among the pagans were many who were skilled in logic, grammar and rhetoric, but whose character was unchanged by the truth they claimed to know.
For who of those that reduce syllogisms, and clear up ambiguities, and explain etymologies, or of those who teach homonyms and synonyms, and predicaments and axioms, and what is the subject and what is the predicate, and who promise their disciples by these and such instructions to make them happy; who of them have so purged their souls as, instead of hating their enemies, to love them; and, instead of speaking ill of those who have reviled them…to bless them; and to pray for those who plot against their lives? On the contrary, they never cease with evil intent to search out skillfully the secrets of their art, and are ever bent on working some ill, making the art of words and not the exhibition of deeds their business and profession.

Athenagoras proceeded to contrast this way of apologetics with the Christian manner, which was a combination of sound argument and pious living:
But among us you will find uneducated persons, and artisans, and old women, who, if they are unable in words to prove the benefit of our doctrine, yet by their deeds exhibit the benefit arising from their persuasion of its truth: they do not rehearse speeches, but exhibit good works; when struck, they do not strike again; when robbed, they do not go to law; they give to those that ask of them, and love their neighbors as themselves.
Athenagoras was highlighting a very important truth: apologetics is not all about rational argumentation. It is also about a Christ-like life that stands just as much in contrast to the lives of the heathen as a sound argument. He also encourages us that even if we don’t know the answer to every challenge brought against the Christian faith, the best response is not always an argument to begin with. Sometimes the best response is Christ-like love, forgiveness, compassion and good works. This should hearten every believer that doesn’t feel that he can always give an answer to those who question his faith. We can all live godly lives of character and good works. That will go a long way toward giving an apologetic that will add much power to our logical arguments.
