As overheard at bedtime tonight

I was singing "It is Well" to Jack at bedtime, and we were on the verse that says, "my sin, not in part, but the whole."

Jack: What does "not in part but the whole" mean?
Me: Hmmm . . .well, it means that Jesus died to save us from ALL of our sin, not just part of it.
Jack: What sin?
Me: Well, everything we do that is disobedient to God. It's called sin.
Jack: Why did those bad men put Jesus on the cross?
Me: They didn't understand who he was. They didn't believe that Jesus was who he said he was.
Jack: Because they were skunks?
Me: Yes, because they were skunks.
Jack: I believe Jesus. Not the skunks.
Me: I'm so glad to hear that.

He reflected for a moment and almost fell asleep.

Jack: So, who did Moses die for?
