The Briefing, a magazine published by matthiasmedia, is a most excellent publication. You can read a great deal from it online by clicking the link above. While hailing out of Australia, you'll find so many things completely and utterly relevant to life as a Christian in these United States. I highly commend both, matthiasmedia and The Briefing to you.
Sandy Grant has a great piece, posted just today, in reaction to an article published by a Sydney newspaper by a woman (?), Fenella Souter, who sought to debunk Christmas as simply a myth, with no true historical roots at all. Grant's response is a marvelous example of how to give a reasoned response, pointing out the glaring errors of which Souter is guilty, and genteelly making the case for the historical fact of Christ's incarnation. By simply pointing out that Souter hardly cites any references for her claims, she has already doomed herself to be taken seriously.
I've been participating in a Bible study on apologetics recently. It's published by RZIM, the ministry arm of Ravi Zacharias. While being a bit over my head at times in the philosophy department, it has still been a delightful study. At the same time, I've been re-reading Gregory Koukl's amazingly helpful book, Tactics: a game plan for discussing your Christian convictions. Given the tactics Koukl presents throughout his book, he would greatly appreciate what Grant has done in seeking to call into question a seriously flawed argument from Souter.
I strongly encourage you to read the article and find yourself prepared to give a defense for the reasons you believe Jesus Christ is the Son of God, come in the flesh, born of a virgin in the city of Bethlehem. Many would read an article like Souter's, accept it as a serious critique of Christianity and the teaching of the incarnation and never bother to THINK about whether anything SHE says is true or not. Be prepared!
