Christ commissioned His followers to take the gospel to the whole world (Matthew 28:19-20; Mark 16:15). Apologetics plays an important role in helping us fulfill this commission.

Evangelization means communicating the truth of Christ. Sometimes this truth generates questions and objections about the Faith. Apologetics addresses these concerns. the apologist task is to reveal the mental barriers people sometimes have to the gospel. Man cannot generate faith, but used only by God to help create the conditions which place a person with an opportunity to hear the gospel. Once that is done, it is up to the Holy Spirit to touch the heart and mind of the person to believe. The holy Spirits job is to release saving faith.

Christian apologetics is the field of study concerned with the systematic defense of Christianity. The term "apologetic" comes from the Greek word apologia απολογία which means in defense of. Therefore, a skilled person involved in Christian or Bible Apologetics is a defender of Christianity. Those who engage in Christian apologetics are called "Christian apologists".

Christian apologetics have taken many forms over the centuries, starting with Paul of Tarsus, including writers such as Augustine of Hippo and Thomas Aquinas, and continuing currently with the modern Christian community, through the efforts of many authors in various Christian traditions such as C.S. Lewis. Apologists have based their defense of Christianity on favoring interpretations of historical evidence, philosophical arguments, scientific investigation, and other disciplines.

This Classical Greek term appears in the Koine (that is, common) Greek of the New Testament. The apostle Paul employed the term "apologia" in his trial speech to Festus and Agrippa when he said, "I make my defense" (Acts 26:2). In the English language, the word apology, derived from the Greek word "apologia", usually refers to asking for forgiveness for an action that is open to blame. Christian apologetics are meant, however, to argue that Christianity is reasonable and in accordance with the evidence that can be examined.
