Apologetics simply is a reasonable defense of the Christian faith. The word is derived from the Greek noun apologia and means “a defense.” Apologia and its verb form apologeomai are used nearly 20 times in the New Testament, often in the classic legal sense, but more importantly to describe the call of God to all believers to defend the Christian faith with gentleness and respect (1 Peter 3:15-16).
But how is sound doctrine applied practically? Put another way, what good is Christian apologetics?
Apologetics has at least four practical applications. We may use apologetics to:
Build. There is a positive case to be made for Christianity, and apologetics helps us get there.
The Bible, history, archaeology, and other sources help establish that a real person named Jesus burst onto the scene 2,000 years ago. He claimed deity, performed miracles, spoke the truth, modeled compassion, died on a Roman cross, was buried and rose physically on the third day. His coming to earth was the most important event in human history.
Further, apologetics helps us know who God is; who we are; why there is purpose in life; how we can be restored to a right relationship with our Creator; why we can face death without fear; and what God is doing about evil in the world.
