Boo, Moses, and the Gospel

Last night at bedtime Boo and I were reading bible stories. We are reading out of two different bible story books right now. One is very simplistic and one is closer to the original language of the bible. From the first, more advanced one we read part of the story of creation. When we got the the part about the seventh day, and how God made it holy, I stopped to check for understanding. He did not know what the word holy means. I explained that it means set apart, made different than the others. Then I asked him what was different about the seventh day. I got the blank stare. Then I rephrased the question.
"What did God do on the first six days?"
"He made all the things in the world."
"And what did he do on the seventh day?"
"He took a rest."
"So what is different about the seventh day that makes it holy?"
"God rested."

We moved on to the other story book where we picked up from our previous reading about Moses. We read about Moses growing up in the palace, then running away, then seeing the burning bush. When God spoke to Moses he told him to remove his shoes because the ground was holy ground. I paused again to check for understanding. Again, we discussed the meaning of the word holy. I asked him what was different about that particular ground where Moses was that made it holy. He thought and studied the picture. His response was "It was made of sand instead of sidewalk." I bit my lip, stifled my giggle, and continued.
"Well, that's one thing that's different. But what special thing happened in that place?"
"God talked to Moses."
"That's right!"

We also talked about how we would feel if God showed up and talked to us. Then we went on with the story. When Moses approached Pharaoh (In this book described as "the mean king") and told him that God said to let the Israelites go, it really bothered Boo that the king said no. He couldn't understand why the king would be mean to the Israelites, why he wouldn't listen to God. His tender heart shone through as he pointed to the picture in the book and traced his finger down from the top of the page onto the face of the angry looking Egyptian king, and he spoke the simplest, most sincere gospel message I think I have ever heard. "He needs God's love."
