The word "apologetics" is derived from the Greek word "apologia" which means to make a defense. It has come to mean defense of the faith. Apologetics covers many areas: who Jesus is, the reliability of the Bible, refuting cults, biblical evidences in the history and archeology, answering objections, etc. In short, it deals with giving reasons for Christianity being the true religion. We are called by God to give an apologia, a defense: "but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence," (1 Pet. 3:15).
