What's apologetics? It is having an answer for those who ask us of our faith. For example, do you have reasons why you believe the Jesus rose from the dead? Or why you think the Bible is trustworthy? Or you think that the biblical definition of marriage is right? In all these areas, we are called to have answers.
1 Peter 3:15 says this, But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear.
Note one thing here, all Christians are commissioned to have an answer! Feel free to share your stories of what people asked you and how you responded, so we all can learn!
