What is heaven like?

Tonight as we were finishing supper the boys started asking questions about heaven. I think it was sparked by a song on the radio. Somehow they have decided heaven is up in the air, amazing because I have never given them that idea.
Anyway, Isaak asked if a rocket could get you to heaven. No I answered, only Jesus can get you there. I reminded them about Jesus dying on the cross and rising from the dead. Then I told them Jesus later went to heaven to prepare a room for each us who called Him a friend and had him in our heart. Isaak asks will there be a manager in my room in heaven? And what about the donkeys? Samuel laughs at him and says he is silly, a year in age sure makes a difference here.
I kept the conversation going and asked if they thought Noodles (our dog) would be in heaven. Isaak said no, Samuel said yes. Then I asked about cows in heaven. Saumel said they would live on the farms.
I also mentioned somewhere in here about the streets of gold. Samuel said can we walk on them or are they like little sprinkles. He also said he was worried about walking on the clouds. Isaak returned to the question, Are you sure a rocket can't get to heaven?
This is one of my favorite things about being a parent, not only the cute things they say and do, but watching their hearts grow in knowledge and love for our awesome God.
