The English word "apology" comes from a Greek word which basically means "to give a defense." Christian apologetics, then, is the science of giving a defense of the Christian faith. There are many skeptics who doubt the existence of God and/or attack belief in the God of the Bible. There are many critics who attack the inspiration and inerrancy of the Bible. There are many false teachers who promote false doctrines and deny the key truths of the Christian faith. THE MISSION of Christian apologetics is to combat these movements against the truth, and instead promote the Christian God and Christian truth. There is no excuse for a Christian to be completely unable to defend his or her faith. Every Christian should be able to give a reasonable presentation of his or her faith in Christ. Not every Christian needs to be an expert in apologetics.
