In our neighborhoods and around the world, there are people who haven't heard about Christ or who are actively rejecting him. We have a responsibility, given to us by the Lord, to share our Christian convictions with these folks and to try to bring them to the faith.
So, what happens when you do this and the person you are speaking with asks you a question, or challenges your view?
Do you answer it?
The important question is: will you do this well? or will you do it poorly? Will you help this unbeliever think about Christianity in a better way or will you add to their confusion?
The heart of apologetics beats for these moments. It is a branch of theology that exists to help Christians share their convictions thoughtfully, meaningfully, and with relevance. Apologetics will give you the tools to get better at these conversations so that we can have confidence in sharing Jesus.
I suppose we could ignore their questions or challenges and just keep on talking to them as if they hadn't said anything. We could treat them as one evangelistic contact among many and write them off as too stubborn to follow Jesus.
Or we could treat them as a human being made in God's image who simply has an honest question or is repeating a challenge that they heard somewhere.
What if your thoughtful response was what made the difference in that person's journey to Christ?
