Never before has apologetics been needed more. The Judeo-Christian framework in which the gospel alone made sense has been destroyed by secularism, pantheism, and post modernism. We are attempting to preach that the gospel is the absolute truth of God, that Christ is the Son of God, that his resurrection is a supernatural act of God to a generation that does not even believe in God, not the theistic God of Scripture who alone must be embraced for salvation. As Francis Schaeffer insisted, we must do pre-evangelism before we can do evangelism effectively. We need to stop apologizing for the gospel and start doing apologetics for the gospel.
The Barthian fideistic aversion to apologetics must be overcome. We need to obey the biblical mandate to give “a reason for the hope that is within you” (1 Pet. 3:15), “to contend for the faith” (Jude 3), and to “know how you should answer each person” (Col. 4:6). Of course, the Word of God, like a lion, does not need to be defended; it merely needs to be expounded. But that is not the question, which is: Is the Bible the Word of God? No Christian would accept the claim of a Muslim that “the Quran does not need to be defended; it merely needs to be expounded.” And neither should we expect them or anyone else to accept without evidence our claim that the Bible is the Word of God.
We need to follow the example of the Master Apologist, our Lord and Savior, who gave witnesses, performed miracles, pointed to fulfilled prophecy, and reasoned with his opponents in favor of the truth He presented. If our Lord saw the need for apologetics throughout His ministry and did it in many different ways, then how much more should we? – Norman Geisler (from the forward to Reasons for Our Hope, by H.
