For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
An article called The Problem with Apologetics is a good example to why practicing apologetics is not only unnecessary but dangerous. If you took the time to read that link, it's pretty sobering isn't it?
The whole point of apologetics is to prove God to a rebellious mind. But think about it in another context. Nobody walks into an art museum and publicly declares that the paintings evolved right onto the walls. Paintings insist there was a painter, Creation insists there is a Creator. I believe the whole matter is settled in Romans chapter one. Everyone knows and understands God through His creation. Everyone. So doesn't debating and "proving" God to fools make one a fool?
It may be a misguided desire to see lost souls come to Christ, but I'm inclined to think that debaters like to feel intellectually superior. But whatever the reason, causing a sinner to lose an intellectual debate does not impel him to fall on his knees in worship and reverence and humility. Jesus is a sinner's only hope.
While evangelism reaches the conscience - apologetics deals only with the intellect.
Therefore I believe apologetics is merely an exercise in pride. And debate is its ugly twin sister. Both are vanity which the word of God commands us against.
But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain.
Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, DEBATE, deceit, malignity; whisperers.
When a believer is tested and tried, the world is watching. They want to see if the fruit is "real". When real grapes are squeezed, they ooze juice while plastic grapes only crack. Our testimonies are being lived out for the world to see and real Christians are not told to "apologize" or "defend" their faith. but to earnestly contend for the faith.
Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints..
So as I see it, we should be studying the word of God, letting our light so shine that others might see our good works and glorify the father, and contending for our faith.
