"According to the American Heritage Dictionary, apologetics is “formal argumentation in defense of something, such as a position or system.” A Christian “apologetic” is not an apology as we usually use the term, that is, to say you are sorry for something. We use the word “apology” in the sense that we give a defense of the Christian faith. Apologetics comes from the Greek word apologia, “to give an answer.” 1 Peter 3:15 gives us the defining statement: “But in your hearts set apart Christ as Lord. Always be prepared to give an answer (apologia) to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect.” The Scriptures do not divorce the content of apologetics from the character of the apologist. The apostle Peter, under the inspiration of the Holy Spirit, knew the hazards and the risks of being an answer-bearer to the sincere questions that people would pose of the Gospel. For that very reason the Scriptures give us a clear picture of the apologist: one who has first set apart Christ in his or her heart as Lord, who then responds with answers to the questioner, and does so, with gentleness and respect."
