Why?

I had two young Korean men come by tonight and ask me why I thought this most recent tragedy had taken place in our world.

I answered that it was because there was evil in our world and that our only hope was in Jesus Christ.

They continued to go to scripture and asked me questions about it, yet they seemed very blown away by the fact that I had an answer for every question. Also that I didn't need my Bible to share scripture with them in my answers.

It was very much a GOD moment, I did ask them if I could ask them a question.....which was since I knew the scriptures they were talking about what was there reason for asking me their questions. You know I NEVER did get an answer and I am pretty sure they were from the same church like the others who have tried to witness to me.........even knowing that I am a Christian. Or maybe they asked because they really don't know what they really believe so they were asking question to help themselves understand the Word. They asked if they could come back again to finish asking me about the scriptures.

Now why would someone want to come back to witness to someone who obviously knows the Risen Christ? Can anyone answer that for me?
