If this were the only reason to do Apologetics, it would be reason enough. By the end of this class, you'll be able to identify specific Bible verses that command Apologetics. You'll also be able to understand how the Greek word “Apologia” is used in Scripture.

Apologetics is not optional. Every follower of Christ is instructed, commanded to be an apologist. You might be thinking: “well where does it say that?”. Well, I'm glad you asked.
Let me give you a few verses to back this up. Probably the most often-cited passage comes from the Apostle Peter. He writes: “
But in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect”. That's 1 Peter 3:15 (ESV).
The Greek word translated “Defense” there, is Apologia. It's used 8 times in the New Testament and literally means a formal defense or reasoned argument for one's position. My favorite passage on this subject comes from Paul. He says:
“For the weapons of our warfare are not of the flesh but have divine power to destroy strongholds. We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ”. 2 Corinthians 10:4-5.
Did you know that there are arguments and lofty opinions that are raised up against the knowledge of God? And your job is to destroy them. The arguments and opinions, not the people. Paul also tells the church of Philippi that they're all partakers with him of grace, both in his imprisonment and in the defense and confirmation of the Gospel. (Philippians 1:7).
Similarly Jude, he says that it was necessary for him to write appealing to contend for the faith that was once for all delivered to the saints (Jude 3).
So as we've seen, God commands Apologetics. Therefore, those who refuse to make a defense or answer each person or contend for the faith, are disobeying God's command. And that alone for the Christians, should be reason enough. So, why Apologetics? Quite simply: The Bible commands it.
