3 Reasons Why We Do Apologetics


If we love Jesus and take what he said seriously we’ll listen to his spokesmen, the apostles. And the passion of the apostles was twofold. First, they wanted Christians to know the riches of God’s grace.  Grasping the gospel was of “first importance” (1 Cor. 15). Second, they wanted Christians fueled by the grace of the gospel to go out and tell people about it.  King Jesus, welding his unique authority as the risen and rightful ruler of creation, commanded his people to spread out and fill the earth with disciples (Matt. 28:18-20). Jude 3 urges us to contend for the once-all-all delivered faith. Paul modeled for us what it looks like to tear down strongholds and every lofty opinion raised up in opposition to God (2 Cor. 10:4-5). And lastly, Peter provided God’s kingdom people with the directive to always be ready to give an account for the hope they have within (1 Pet. 3:15).

Taking these words seriously, both in theory and practice, gets to the heart of Christian apologetics. But is there any motive greater than mere duty in defending the faith against all would-be contenders? Let me suggest three benefits to studying and practicing apologetics.

First, apologetics encourages the believer to develop a distinctively Christian theory of knowledge. Apologetics deals with defending and commending the Christian faith. As a result, it deals with knowledge claims. We claim to know multiple things, things like God exists, that he is a trinity, that humans are his fallen image-bearers, that Jesus of Nazareth is the Son of God, and that this Jesus rose from the dead, etc. We don’t have faith in faith. Apologists are commending a concrete faith arising from a concrete source (the Bible).

When we’re talking about knowledge claims (religious or otherwise) we’re dealing with issues in the field of epistemology. Epistemology is the subdivision in philosophy that explores knowledge and the questions that come along with exploring what that means. These are some epistemological questions: How do we know things? How we determine true knowledge from opinion? How do we know truth? In the history of philosophy many schools of thought have put forward their epistemologies, but the Christian apologists shouldn’t be tossed back and forth with each passing philosophical fad.  We can only embrace an approach to knowledge that conforms to the Bible.

Apologetics should ask the standard epistemological questions (how do I know? etc.) and look for their answers with an open Bible. By doing this we demonstrate a submission to God’s word as our ultimate standard not only for so-called “religious” knowledge, but for all knowledge. Likewise, in doing this we “love the Lord our God with all… our minds” (Lk. 10:27). Scripture is filled with passages that address our thought-life. We are to “take every thought captive” (2 Cor. 10:4-5) to Christ “in whom are hidden all the treasures of wisdom and knowledge” (Col. 2:3). It also speaks of the saving knowledge of God that Christians have, as well as the paradoxical nature of the unbeliever’s knowledge of God.

Second, apologetics strengthens, confirms, and emboldens Christians in their faith. When Christians follow the 1 Pet. 3:15 command to defend their faith several things happen. First, their faith is confirmed. Those who have professed Christ for any length of time know that doubt occasionally creeps in and can cause them to second guess the truth of Christianity. The careful study of apologetics brings encouragement to the believer, reassuring them that their commitment to Jesus is not based on myth, speculation, or fairy tale, but instead is grounded in real history. Furthermore, when we see that only Christianity provides a true understanding of the world we come to trust our Creator and Lord with renewed vigor and strengthened faith.

Finally, the study of apologetics emboldens us for engagement with non-Christians. Here I’m not simply referring to apologetic debate, but also for personal evangelism and other venues of Christian/non-Christian dialogue. If the message of creation-fall-redemption in Christ is true, and the goal of apologetics is to demonstrate the truth of the Christian worldview, then pouring time into knowing how to handle objections, unbelieving philosophies, and various other unchristian ways of thinking is a vital means the Holy Spirit may use in communicating the gospel in a sin-sick world.

Third, apologetics serves as a vital aid in the work of missions, evangelism, and cultural engagement. How is this different from what was written in the paragraph above? There I was addressing the emboldening Christian confidence in encounters with non-Christians. Now we’re switching our emphasis a bit and focusing on the help apologetic provides in Christian understanding.

Evangelism. In the course of familiarizing oneself with the case for the Christian worldview we must familiarize ourselves to common misunderstanding, misrepresentations, and objections to the faith. This is a matter of love, since knowing what weighs most heavily on the minds and hearts of unbelievers demonstrates that we take them seriously. More often than you’d imagine, you’ll encounter the same objections and questions repeatedly. We should take stock of such common objections. Knowing these objections greatly reduces the chances of being caught off guard. It will also communicate that we’ve put some serious thought into our faith commitment. Many unbelievers haven’t ever heard an informed, rational defense of biblical faith. Here are some more specifics on how knowledge of apologetics aids relating to non-Christians. We should know why we believe the Bible is God’s book, why Christianity is different from other religions, and what practical difference does it make for the potential convert.

Missions. Apologetics also helps in the work of missions. Those to whom we commend the faith may be under serious social pressure to remain as they are, whether in intensely religious countries or secular nations. They need to know why they should risk persecution for committing their life to Christ. Are they committing social suicide? Are they committing intellectual suicide? Another major issue for a theology of missions is the question of religious pluralism. Are all religions the same? Are they all legit pathways to God?[1]

Cultural engagement and the final apologetic. Christians are to be “in” the world, yet not “of” the world (Jn 17:14–19). We live among unbelievers as spiritual ambassadors for Christ’s kingdom. We shouldn’t live in step with the agenda of unbelief. Apologists must be counter-cultural, developing a distinctively Christian critique of cultural trends as well as positively commending biblical alternatives. This takes a lot of study, effort, and prayer. Lastly, non-Christians need to see how we love one another. They need to see and experience for themselves that we, like the Master, come not to be served, but to serve (cf. Mk. 10:45). The manner with which we speak, both to other Christians as well as to non-Christians, conveys a lot. The church is Christ’s body on this earth. Do we reflect His character? Non-Christians aren’t naive. They notice insincerity and pride. But both are reasoned responses as well as our observed behavior we convey a powerful message: This is what God is like.

Let’s not give false testimony.





[1] Of course, the answer to this question is “no.” It’s both philosophically wrong (because so many religions make contradictory claims), and biblically dangerous (Jesus is the only way to God, cf. John 14:6, Acts 4:12). But the point is that as we study apologetics we learn both how to develop this claim (so the unbeliever sees the Biblical rationale for it), as well as how to persuasively communicate it.
