I never knew what a Christian Apologist was until I got born-again. It means… to defend Christ and our Christian faith. Cool stuff. I especially like Bobby Conways “One Minute Apologist” clips on youtube. They are great. Only a few minutes long and easy to watch. Very good learning tools for Christians.
There are so many brilliant Apologists out there to learn from like: C.S. Lewis, R.C. Sproul, Lee Strobel, Hugh Ross,Josh McDowell, Gordon Clark, Mary Jo Sharp, Ken Boa, Kyle Butt, Mike Mason, Norman Geisler, Gene Cook, Dinesh D’Souza, John Lennox, Fazale Rana, David Robertson,Simon Newcomb, etc, etc, etc.
Christian apologetics is the defense of the Christian faith through logical arguments. The term comes from the Greek word apologia, which means “defense”. The expression “Christian apologist” therefore does not mean that someone is apologising for or on behalf of Christianity as is sometimes thought, but that he or she is defending and justifying it. There are a number of subfields within apologetics. Some apologists specialize in internal biblical consistency (such as JP Holding, owner of tektonics.org), others in scientific defenses of the Bible, and still others in historical or philosophical defenses of Christianity (such as Gary Habermas or Lee Strobel). Christian apologist JP Holding has recommended that prospective apologists choose one area of focus rather than trying to be a “jack of all trades”.  Some feel that faith alone should need no justification, however, many feel that Christians should be prepared to defend and spread their faith by intellectual means, especially as many people will not accept Christianity without a “rational” reason to do so.
“Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, keeping a clear conscience, so that those who speak maliciously against your good behavior in Christ may be ashamed of their slander.” 1 Peter 3:15-16.
