The Bible itself contains truth statements that conflict with other worldviews. Jesus Christ never defended His position. Instead, He confronted the worldviews and beliefs of those He came into contact with head on. As evangelists, Christians are charged with attacking opposing belief systems. An apologetic argument is based on the foundation that the Bible is true in its entirety.
A previous article offered an overview of Textual Criticism. In it, arguments were formulated based off of the manuscript record that what was written in the New Testament is actually what was written. This article deals with the truth of what was written. While written words can oftentimes be falsified by authors for personal gain, the writers of the New Testament had nothing to gain from their writings.
The Apostle Paul is credited with authorship of 13 books of the New Testament. What is unique about these books is that they are letters written to various churches and people that Paul was in contact with. When critiquing literature, the benefit of the doubt is given to the author unless proven otherwise by external or internal evidence that would falsify statements within. Here's where intentions come into play.
Did the Apostle Paul knowingly write scripture? The answer is no. He wrote letters to people he knew and loved and those letters were agreed upon prior to the canonization of the Biblical text.
Did Paul stand to gain anything by distorting the truth? The answer is no. One thing is for certain, that Paul was martyred, yet he did not deny any statements or claims that he made. Many people die for a cause, whether that cause is real or not makes no difference. What matters is that those who are willing to be tortured and die for their beliefs is indication that they really believed what they said they believed. Only a fool would die for a cause they knew was a lie.
Apologists, get ready to attack. A defensive position will always lead to cherry picking and spear chucking. An intellectual satisfying knowledge of the Christian worldview and apologetic arguments will equip the evangelist with enough ammunition to destroy opposing worldviews without the need to argue particulars.
