According to 1 Peter 3 : 15, Christians are commanded to always be prepared to make a defense to anyone who asks for a reason for the hope that is in us. The Christian discipline of apologetics is learning to explain and defend why we believe what we believe. God does not need anyone to defend Him, of course. What Christians are called to defend is the hope that is in us. There are good reasons for believing in God, and Christians are commanded to have them at the ready.
All Christians are commanded first of all to proclaim the good news that “The Son of God became a man to enable men to become sons of God,” in the glorious words of C.S. Lewis. Sometimes, all unbelievers need to hear is “a simple gospel presentation” to believe. In this increasingly anti-christian era unbelievers are skeptical of the gospel and question the truth claims of Christianity. That is why all Christians are also called to defend the good news of salvation through Jesus Christ.
Apologetics is nothing new. On the day of Pentecost, when the Holy Spirit fell on the first Christians, some were amazed to hear God praised miraculously in all the languages of the Roman world. Others mocked, saying the Christians were only drunk. Peter defended the outpouring of the Spirit by quoting the prophet Joel. He pointed out the miracles of Jesus, and boldly testified that he had witnessed the risen Savior. Fulfilled prophecy, miracles, the eyewitness testimony the Apostles, and the resurrection of Jesus remain key points for Christian defenders today. Peter used apologetics, and God used Peter to save about 3,000 people on that day.
Do you want to lead people to Jesus? Ground yourselves in the redemptive message of the Bible first, and learn apologetics second. It’s a wise person that wins souls (Proverbs 11:30).
