I want to be a missionary now

Everyday that Seth comes home from preschool, I ask him what he did that day. He can't usually tell me much of anything during the car ride home, but later in the day and sometimes days later, he'll mention something about preschool. He has been talking about "Danny", a boy that he says is "bad", but he doesn't ever give me any specifics about what Danny does that makes him bad. So I don't really press the issue. I just tell him to be nice to Danny but to not do the bad things that he (Danny) does. So yesterday, Seth says to me, "I decided I needed to share the gospel with Danny." The thoughts running through my head were, "Oh, no! What did he say? And at preschool of all places?" Here is how our conversation went-

Seth: I was teaching Danny about Heavenly Father and Jesus.

Me: Really? What did you teach him?

Seth: Well, I was teaching him how Jesus died for us.

Me: Wow! What else did you teach him?

Seth: Well, he thinks heaven is far away in the sky. But I told him that when you pray heaven can be close around you. But he still thinks that heaven is far away in the sky. Next time I go to school I have to teach him some more.

Me: What are you going to teach him?

Seth: I'll find out.

"Yea, even babes did open their mouths and utter marvelous things..."

Oh, that we all could be so bold. I have never done anything like this.
